So far, I have recognized in this movie:
Bowser from Mario
Eggman/Robotnik from Sonic
M. Bison and Zangief from Street Fighter
Clyde from Pac-Man
Cyril from House of the Dead
Nef from Altered Beast
Kano from Mortal Kombat
Q-bert from Q-bert
Chun-li and Cammy from Street Fighter

And quite a few more that I don't remember or haven't seen/recognized yet.

Shadow from Mortal Kombat is to the main character's left.

So...Many...Classic Video game characters...I think i see the angry sun from Mario. M Bison. And more.

The trailer showed Bowser and Eggman too.

I know. This is going to be Good

I must respectfully disagree with you to the fullest degree possible. This year's show was pretty bad but there were still some fantastic diamonds in the rough.

It just feels like they've forgotten who their target audience is. I didn't pay that much attention after the singing and dancing routines that had nothing to do with video games.

<--- Only game at E3 I was interested in. (from what I saw anyway)

E3 doesn't organize the individual press conferences. That's up to the people running the press cons themselves. Yeah, after all this time they still show retarded ass sports, dancing, and other various things that we don't give a shit about. I am indeed surprised they haven't figured it out yet, but that doesn't stop me from enjoying what's there and worth in enjoying. (Like the fact that NOBODY clapped at the end of Flo Rida's performance. That felt so great.)
