My predictions start at the top with "possible" all the way down to "off the hook never-going-to-happen craziness".

• Kid Icarus revealed as a 3D platformer/shooter/flying game.
• Wario Ware "Unbalanced" announced. 50% of the minigames are balance board controlled.
• Mario Tennis or Golf announced with a controller shell packaged with the game (racket and club, respectively).
• Black Wii consoles and remotes revealed.
• Metroid Dread finally unveiled as a WiiWare title with SNES style graphics, if Nintendo wimps-out, it will be revealed as a DS title.
• Retro Studios are restarting production on their ill-fated Gamecube "Car Combat" game for Wii, now to include online battling.
• An IR-based Star Fox game will be announced which draws inspiration from the SNES and N64 classics. The game will possibly feature a "family-friendly" mode and perhaps even an online dog-fighting mode.
• A sequel to Mario Galaxy! Well, more of an expansion pack than a full blown game; I’m sure they had plenty more planet ideas that didn't make it into the original.
• A mini USB memory stick/hard drive adapter that slots inside a newly designed base that the Wii sits on, with a blue light on the front.

Some of my crazier predictions are as follows:

• An official Wireless nunchuk controller revealed for $30.
• A DVD channel announced for purchase on the Wii Shop Channel, for 1000 Wii points.
• A new DS will be announced for Christmas with its own built-in shopping channel. Game Boy and GBA games will be available for purchase and will be downloaded directly onto the system's internal flash memory.
• Shigeru Miyamoto quits and leaves for Tecmo to work on the next Ninja Gaiden game for Xbox 360.
