Perhaps the biggest announcement of the summit was....

The lack of a big announcement was the biggest announcement? I could actually see Cammie coming on stage and saying that :P

We already basically know what Nintendo will throw at us for the holidays and that's Wii Vitality/Wii Relax (whatever it's going to be called) and Zelda Wii. I think E3 will be pretty big this year, my guess it'll include:

- Metroid: Other M on stage demo as the game releases a couple of weeks after E3
- Vitality Sensor final hardware and software
- Retro Studios next title with a tentative 2011 release date
- Pikmin 3 announced with a tentative 2011 release date
- The Legend of Zelda: Wii unveiled with full stage demo and trailer
- Next generation Pokemon titles shown off
- A couple of brand new Nintendo IP's for DS and DSi to revitalise lagging software and hardware sales

Probably a couple more little things for WiiWare and DSi but that'd probably be the bulk of it.

Pretty much what's most likely to happen, except i'd add in something about Golden Sun, Reginliev localization, Xenoblade/Last Story stuff, and change the Retro Studios date to 2010.
