I didn't read all the posts, but when the Wii was announced and we were still speculating on it, I suggested that it have a projector inside so you wouldn't even need a T.V, and gives it a reason to be taken outside the home.
Nintendo tried the 'take your console to your friends house' with the GC's (some would say obtrusive) handle, and it didn't work. But with how small and common projectors are getting, and their ability to display 1080p we could have a WiiHD with projector. And projectors also have the ability to display 3D, but the question is; can Nintendo pioneer glasses-free projection 3D?
I would think if such technology was readily available movie studios would have adopted it already, but it would cool if Nintendo could develop (and possible patent) this technology.
Both the PS3 and 360 have gotten midlife facelifts, but the Wii has not, so is it due for one, or is Nintendo holding back to release its successor. Nintendo does like to surprise people (maybe just to boast at how well they can keep a secret) so it would be cool to see the next Wii (facelift or successor) at E3 2011 and it would be cooler yet if the 3DS was somehow the next Wii... I'm just saying.
