With the success of accessories on the Wii, I think they'll release a new accessory for E3. But I thought it over and I can't really think of what's needed. The only thing that came to mind is a power glove, maybe for some beat 'em up game. What do you think?

is there a mic for it yet...

Well, yeah, but They're USB! we need a Wireless mic Headset, or one that plugs into the Wiimote w/ a passthru

there is no mic for online use tho...

HEAD TRACKING

do you mean head tracking glasses? that would be cool i guess

DS player..... just kidding. The Hard Drive people keep complaining about is probably what it needs.

Ninty would love a new peripheral to follow up after WiiFit. I can think up a few potentials which would help keep the momentum going:

 - Wiimote II: a "better" Wiimote, more accurate and capable of 1-1 control - would be bundled with WiiSports II

 - WiiBike: what about some of exercise bike - with leaning, controllable handle bars, etc. Another WiiFit type peripheral, also great for WaveRace, MotoGP, and motorsports games

 - WiiChat: a "phone", with a number pad, etc. Specifically for VoIP applications, maybe with an optional headset so it can be used by games.

There might be potential for a camera, keyboard, mic/voice recog, and a few others?

Extra storage is nothing - the Wii already supports these in hardware, its just software needed. 

I wouldn't be surprised if the 360mote beats Nintendo to 1-to-1 control Shams. Imagine playing Halo Wars with mouse-like precision while waving your arms in the air from your couch.

Well I don't know about you guys but there are those days you just can't decide if to play the new released game or to have sex. So a vibrator addon which you can give to your gf and whilst you play a game ie ssbb nmh zelda etcc that thing goes of like crazy and gives her some loving too whilst you wave aroudn the wii remote playing the game it makes the addon go off too.
