Please give us a Keyboard for web surfing! Seriously, I'd really appreciate that ><

Most likely:

 - Wii mass storage device (either hdisk or better support for SD card)
 - microphone (almost certainly) - be it "built-into" the Wiimote, or a little snazzy add-on

Less likely:

 - a new Wiimote that doubles as a VoIP capable phone (NOT a mobile!) and a microphone

Unexpected (but then this "is" Nintendo with their Blue Ocean strategy...):

 - new handheld (GC games compatible), take on the PSP market
 - upgraded revision of the DS (digital distribution support, etc...)

A keyboard would be cool to (and very easy to implement - any Bluetooth enabled kb could work).

I'm guessing more Wiimote attachments. We know one is coming with Wii health, I'm sure we'll get a microphone, and perhaps something else cool with a newly announced Wii____ title. I think we're also due for a usb mass storage drive or something like that.

 There is no way it's a follow up to the DS or the Wii it is simply too soon for that, and if it were something that huge we would have heard about it already. Seriously it's absurd with the way the DS is selling that anyone think it's a new handheld. Why would you hurt your existing handheld and compete with a new device when you breaking records left and right? Plus it's too early in the DS's life to bother. 

This looks feasable, but i read the link for the hard drive, and it looks more likely.....I cant wait for Neo Geo games!!!I can't beleive one of those has 330 meg,

I hope nintendo releases a better dame wii-mote!!!!

I hate playing zelda, swinging the sword, then need to press the 1 or 2 buttons..your thumb is on the d pad or A button, our thumbs are not double jointed, lets hope for a better controller soon!

I 3rd that motion.

nothing big

Whatever it is, it'll prob. disappoint since speculation is running higher than anything Nintendo can announce.

I wish Nintendo would announce that all future Wiis will come with 1 GB + internal memory and that they'll support SD cards up to 8 GB through a software upgrade.

this might be an anoouncement, I just wish E3 was open to the public!

Wow, I just did some serching. Neo Geo was released in '91 and had carts that could hold over 700mb.
When I read that maybe its an external hdd I couldnt beleave that. Its funny how a console that was $650 at launch and had a huge amount of storage (SNES bigest carts held 48mb and launched at $200) could die out so quick. Another history that the ps3 has to brake.
