microsoft will for the third year running, have the worst E3 conference. I mean seriously, they just don't get it, people who get hyped up for casual crap don't give a rats ass about E3. E3 is a day for GAMERS. We don't want sales data, we don't kids demoing disneyland adventures, we don't need a half hour demonstration on kinect dance or whatever BS, we want game announcements, game announcements and more game announcements, and if they have a new system then that's different obviously.
and even in the rare occasions where they do show off core games, they spend 20-30 minutes on each one, I mean for crying out loud move on to the next damn game. Nintendo used to do this quite a bit pre 2010 and it was just so lame, there'll be time for us to check out previews and long gameplay footage later, for now we just want trailers and maybe a few short demos, but i hate it when they drag on just to waste time.
I'm sure sony will have a good E3 but to me they kind of have the same issue that microsoft do which is spending far too much time demoing each game, which is boring and frustrating but overall it'll be pretty good. I imagine it'll be very focused on the vita. Aside from The Last of Us and god of war, there doesn't seem to be much else to look forward to for ps3 gamers. Maybe they'll just drop a bomb and have a tonne of surprise game announcements like nintendo did in 2010 when we all thought that there'll be nothing interesting announced for the wii other than zelda...how wrong we were

As for nintendo, well judging from the last two years, they have learned their lesson from 2008, they won't give us sales data, and they won't spend too long on casual crap (if at all), it's just a question of whether they have enough good game announcements for the 3DS and especially the Wii U, because as it stands now, not a single game on the wii u that interests me, and even if they were all Wii U exclusives the only game that would interest me is batman arkham city.
I'm certain that many others feel the same, and that HAS to change by the end of E3. As for the console itself, they've had a lot of good criticism from their fans and journalists (the minority which aren't retarded and sing "nintendo are doomed" every morning), the name, clickable analog sticks/circle pads, new wireless classic controller pack in, I really hope they listen to us and make those necessary changes otherwise revealing the Wii U at e3 2011 would have been a waste of time.
