Sorry for double posting but I have more info. Over in the N-sider forums, a member provided the following link of a patent Nintendo filed.
http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.html&r=2%204&p=1&f=G&l=50&d=PG01&S1=nintendo.AS.&OS=an/nintendo&RS=AN/nintendohttp://img.photobucket.com/albums/v304/mentallyerect/image1.jpgThe following is my thoery on what the patent is talking about. If you look at the first image, you can notice one character has x,y,z labeled next to them. The x,y,z is representing the 3 axis that are used when refering to the third dimention in math. It seems that the top "frame" displays the 2d y and z axis while the bottom one, in relation to the top, displays the full 3d image (x,y,z). Take a look at this quote from the abstract.
"The first frame 77 is set so that selected objects 81 through 84 are positioned inside of the first frame 77 when viewed from a direction of the line of sight. Furthermore, the first frame 77 is deformed in accordance with movements of the selected objects 81 through 84. Specifically, when all of the selected objects 81 through 84 are a predetermined distance away from one side of the frame 77 when viewed in the direction of the line of sight, the side is moved toward the inside of the first frame 77, thereby deforming the first frame 77. "
What I get from that is that in the main frame (77, the bottom frame where I believe the characters would seem to be in 3d) when you move said characters ( 81-84) accross to the end of the frame, the image will, as they call it, distort. By distort, I believe they mean that the whole image will move on foward and the characters instead of being at the end of the frame, will then be in the beginning. An example I can think of is Animal Crossing or Zelda: Link to the Past, where the world is split into grids, when you move from one area to another, the camera would pan over to display the next grid. This is how I envision this 3d display. When you reach the end of the 3d frame, the frame would adjust to show the next grid.
Further along, they make mention of multiplayer games and how they could be inplemented into this display. They basically said the frame would expand much like a camera zooms out, in order to show the full playfeild and all playable characters.
Page 4 is just another demonstration of the 3d plane/"frame".

http://img.photobucket.com/albums/v304/mentallyerect/image3.jpgThe rest of the pages/images seem to show off how the frame would display mutliplayer games. Also, they mention coordinates alot within the images further establishing the idea of a true 3 dimentional plane since coordinates is a way to pinpoint areas in an x,y,z plane.
Other pages of note are 18, and 21-22 (descriptions of images on all pages)
18 shows what I believe to be the projection of the image through the screens
http://img.photobucket.com/albums/v304/mentallyerect/image4.jpgAnother good quote is
"BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to game systems and game programs that cause a game space to be displayed on a display device and, more specifically, to a game system and a game program that changes a display area according to positions of objects. "
Well, thats how I interpretted what I saw and read off the patent. My guess is that this was originally thought up as an add-on for the gamecube but now is being moved on towards the Rev. The current rumors of a dual processor on a Rev could be to better display these 2 frames. I believe this is so becuase Nintendo always puts alot of thought into the design of their systems. They will not go wit a dual processor just to up the graphics, there has to be a purpose for the decision and I think this 3d display patent could be it.
Also, some on the other forum are arguing that this patent is in relation to Zelda:Four Swords. Here's a quote from one of the other members there.
"1) Considering the GameCube is pictured...
2) Considering little guys with swords are pictured...
3) Considering the individuals who registered the patent worked on Four Swords Adventures....
4) Considering Four Swords Adventures uses a different screen setup to display player's screens... (thanks Z64)
5) The logical conclusion to come to would be that (sorry to poop on the parade) this has absolutely nothing directly to do with the Revolution -- but rather Four Swords Adventures on the Nintendo GameCube. That's not to say Nintendo won't utilize this technology for the next generation...but I highly doubt this patent is specifically for it."
My thoughts on this were.....
The Gamecube being pictured just makes me think this was an addon planned for the Gamecube originally. Remember, at one point, Nintendo said they wanted to extend the life of the Gamecube by providing add ons to enhance the experience.
The use of guys with swords in the pictures is just to better illustrate video games. Knights and dragons are commonly associated to games and fantasy. It's universal, when someone sees it, they picture role playing as a main character. They picture a game, board game or video game. If they had put a cruid drawing of a guy jumping and turtles or goombas on the plane, it'll be too specific to a particular game. The use of illustrations of guys with guns would be too violent. The guy with the sword, archer, pendent/item and dragon were just used for illustration purposes.
The tie ins with Zelda: Four Swords is there but I'm not completely sold on it. Zelda: FS was released June 7th and this patent was put forth on July 21st, a month later. Also, the images on the patent have a date on top for Jan 27th 2005. I'm not sure if thats the date the images were added onto the patent though. I hope someone can give me further info on this date. This just further supports my idea that this was created first as a Gamecube addon to extend its life but now is being expanded upon for an unknown (to us) purpose.
If you think about it, this can tie in to the Rev. A true 3d display can revolutionize things. They won't even have to match the graphics quality of the competition. High end graphics will not be able to compete with a true 3d display. The rumors so far are sudjesting that they are not using new tech but are using something that hasn't been applyed to games yet. Also, the talk of the dual processor makes me wonder. If Nintendo were to go with a dual processor design, there has to be a reason or purpose behind the move. The dual processor design is not just there to up graphics. The gyro/motion controller rumor also would fit into this type of gaming, moreso than on the tradition 3d games on a 2d television gaming.
Also, 3d can't be that far off as everyone claims. I remember playing a Sega fighting game at the arcades back in the 90s that used holograms to create a 3d display. The fighters would seem to stand out of the bottom screen. That was back in the 90s though, technology has advanced since then. Anyways, I'm just brainstorming, I'm not exactly sure what can or can not (realistically and economically) be done for a next gen home console.
