I'm not sure what people expected, but I found it to be a reasonably impressive conference. Multiple unannounced exclusives, multiple games shown with game play, nothing but games.
The only part I found weird at all was Alex from Harmonix, who sincerely sounded like he couldn't give a fuck.
THIS
great conference for me: games, games, games and games. no speech, no tv, no kinect, no services, no statistics, no performances, just GAMES
I also liked they way they planned it, from the games about to be released for this year, to the unannounced ones which seem to be beyond 2015.
I really missed Gears, or release dates for Quantum Break or D4. I think they needed more time, 90' felt short for all they have to talk about.
by the way, I expect MS announcing more details for the japanese titles, Scalebound, and D4, as I also expect them to announce new exclusive titles for the japanese market.
overall, great conference
