they would need to unveil, pikmin3 a new zelda,kid icarus and good third party games

I'm actually expecting an Eternal darkness sequel.
That'd be nice.

^ that would be a great anouncement, I love that game

A 2D games series, With Metroid, Wario, Super Mario and Zelda... all in retro 2D with amazing new sprites and effects

Thats a Win for me...

Nintendo already won this year by not announcing a single game for the 2nd half of the year. They'll be announcing 6 months' worth of games at once and stealing the entire show. And of course Reggie will show some graphs that show that Brawl, Kart, and Wii Fit have all broken 5 million, and that his weenis is bigger than ours.

I also expect them to pull back some giant curtain and reveal a couple thousand 3rd party exclusives.

lol ween-is.

He just busts it out during the speach

2d metroid=orgasm./joke

for me we'll probably see

Wii Music
Animal Crossing with full use of Wiiconnect 24
Punch Out
Kid Icarus confirmation
Pikmin 3
New Zelda Wii Footage
Wii 1080 Avalance
Storage Solution fully working and integrated with new look Wii Operating Software / channel system.

This alone would win E3 for me but i'd also like to see

balance Board announced to be sold sperately
New Wii colours with wireless nunchucks, internal storage solution, rechargable wiimotes & dvd player.
these other 4 -5 balance board games (reggie stated there were 10 in development and we've only had around 5 unveiled so far).
Pikmin DS (this will be different to the Pikmin 3)
Players Choice
a new pikmin 1 & 2 with original GC controller support and revised Wii controls to celebrate Pikmin 3 and give the Wii's new audience a taster.

Personally I`m just after an F-Zero game and another "proper" Resident Evil game so those two announcements would equal victory for me.

How does one win E3? F-Zero would be pretty rockin. New Halo game would be rockin. Not sure what Sony has coming up.
