The Wii hard drive sounds plausable, but I can't stop thinking that it's going to be something really anticlimatic like new Wii or DS colours.

It would be probably something small they announce, but I hope for a HD memory external expansion and finally that god-forsaken demo channel! And not only for the VC games.

But indeed we will probably learn that we we're all stupid enough not to notice that our remotes had a microphone in it all along... Like I care though...

There is no way they would tinker with the basic Wii - 0% chance. Not something you do when your product is completely selling out, and you can't meet demand. Would confuse consumers, AND create additional supply chain issues.

Demo channel / extra storage I think are almost certain. Whether its SD card, hdisk or something else... we are yet to see. 

New ROB device. Wii is a multiplayer console, but some people are lonely. With modern AI tech, Nintendo can release a robot buddy that actually interacts with the game, and learns against your moves. It will be called WOB, and it will look like the torso of a Honda ASIMO. It will connect to the Wii via wifi, and be compatible with any game. At night, it will monitor your motions, and calculate precisely when you enter REM sleep each night, and send this information to Kyoto via WiiConnect24. Nintendo will use this information to more accurately deliver you candy.

myabe it's a Sony Wii to replace the Sony PS3?

Interesting, Sony just patented a similar device, Who knows Nintendo might(they have done it in the past)say Surprise, and give us a whole range or hardware add-ons/accessories etc.

I'm going to use mine to cook food.
