I'll start this off by saying...kinda disappointed in general with this E3...it had a lot of potential but ultimately fell short. Not sure how many people kept up with all the stuff as it happened, but I'll try to sum up a lot of the highlights and maybe throw some videos and such in when I'm less tired.
EA: Mass Effect 3 looks great and now has nonsensical kinect support, Battlefield 3 looks crazy good (PC version requires $81926416 computer), new Need for Speed has on foot running segments...on foot running segments, they continue to NOT show actual gameplay of Star Wars Old Republic, and more sports games.
Ubisoft: What a clusterfuck of crap, hosted by an insufferable douche bag.
Microsoft: Kinect, Call of Duty 3 stuff, Kinect, new Tomb Raider which is very Uncharted-like, Kinect, Fable now to be an on-rails Kinect shooter (think Link's crossbow training...you know, the FREE game), Kinect, Dance Central 2 for Kinect, Halo 4 and Halo 1 remastered, Kinect, Gears 3 stuff which is still looking really good, and also some Kinect stuff. This is seriously what this conf felt like...prolly the worse of anything E3 this year...and if that weren't enough to convince you? Minecraft for Kinect...FML.
Sony: "Sorry PSN died", Uncharted 3 and portable Uncharted, Resistance 3 and portable Resistance but more important is a Res 3 PS3 bundle with a 3D tv for $499 which is a pretty damn good deal, Starhawk (Warhawk with space I guess), new Sly Cooper (prolly one of the more exciting announcements), new Star Trek game that looks Mass Effect-ish. New PSP called PS Vita and will be $249 (wi-fi) and $299 (3G) with LittleBigPlanet, StreetfighterXTekken with Cole from Infamous playable, ModRacers, and other games announced. Vita also sported the ONLY announcement of all E3 that got boos from the audience, AT&T will be the official carrier. Overall much better showing from Sony than last year.
Nintendo: Zelda 25th anniversary and lots of talk about old and the few upcoming Zelda games we already knew about, few 3DS games shown, Super Mario (with tanooki suits!), Starfox (optional tilt control) with multipayer that shows everyone's camera, Mario Kart with hang gliders in the karts and underwater driving, Luigi's Mansion, and Kid Icarus which looks way more action-y than I was expecting AND sporting some cool multiplayer. 3rd party reel with Tekken 3D and Ace Combat 3D were pretty new along with some others we already knew about. Then brings the "Wii U" presentation which mainly showcases the new controller which functions as a normal controller, has a touchscreen, can stream the game to the touchscreen (people can change the channel and watch tv while you continue playing), and multiple other functionalities with the screen, in-ward facing camera, and built-in gyro. Smashbros also mentioned for both Wii U and 3DS with possible functionality between the two.
Tried to make this not TOO long...there are obviously many things unmentioned in the conferences and not to mention things NOT announced that are on the show floor (like new Kirby for 3DS and Wii). In any case though, like I had said...disappointed in general. It feels like a lot more could have and should have been shown by everyone. Sadly EA was prolly the best conf cause they were like "omg games games games" but still nothing really new. So yeah, I dunno, pretty indifferent about this E3 in general but I am interested in the possibilities with this Wii U and wonder how well it's gonna do.
