I just read the new miyamoto interview, and there are some very interesting tidbits in there, heres a few highlights
Mario Kart could have been shown in video form there, but Miyamoto said he wanted it to debut at E3, apparantly the game may be finished
Pikmin 2 footage was shown, it has multiplayer
Kirbys Air Ride footage was shown, it looks really fun apparently
Zelda: Wind Waker PAL/US versions will have added features and a few gameplay tweaks that were not in the Japanese version
Nintendo is furthering thier relationship with Namco and Sega, and beggining a partnership with EA

This was at an interview with Miyamoto when he was in London yesterday by the way. Its a very long interview that you can read
here . Its a very interesting interview, i recommend you all read it.
