They’ve released a new trailer (http://www.nintendo.co.jp/n10/conference2010/3ds/lineupMovHigh.html) for a 3DS, along with another one (http://www.youtube.com/watch?v=RPuYwxudQ8A) showing off Street Fighter. There’s also uh, this (http://www.youtube.com/watch?v=KC2QznyN-Bw) trailer for some dating sim.
They’ve announced a few more new games like Megaman Legends 3, Puzzle Bobble as well as a second Resident Evil game (http://www.capcom-unity.com/jgonzo/blog/2010/09/28/resident_evil:_the_mercenaries_3d_announced_for_ni ntendo_3ds) which will feature Mercenary missions from RE4 and RE5 (with online co-op and competitive modes).
Gameboy and Gameboy Advance games will be available on the system as an equivalent to Wii’s virtual console.
If you’ve bought any DSiWare games, you will be able to transfer them to the 3DS.
Really, go to just about any gaming news website (or this live blog (http://www.andriasang.com/e/blog/2010/09/29/nintendo_conf_live_blog/)) and you’ll see all this stuff and whatever else they had at the Nintendo conference.
I’m pretty pumped about this. The new RE games and MGS3 look great.
Edit:

Also, it seems they’ve updated 3 to have a similar sneaking system to what’s in 4 and Peace Walker (you can tell by the ring around Big Boss).
