The event's games presentations were oriented to what is usually called the "Bro gamer" demographic (e.g. Madden/FIFA/CoD) ... It focused on TV, for which many of the core gamers don't care. Contrast this to the PS4 announcement, which had many developers and a lot of talk about how the platform is going to be more "open" for the small guys, and it felt really passionate about the "for-gamers" features. As a gamer, I feel like the PS4 is where the real passion for games is, where someone actually cared to provide tools for the "indie" crowd (who, arguably, are doing the good games these days) ... Meanwhile, microsoft is showing a TV machine, has forgotten the indie channel and has killed XNA. If you don't understand why this was dissapointing for gamers, it's most probably because you are not a gamer yourself I guess. Honestly it felt passionless, pointless and underwhelming. It wasn't a blunder or anything, of course. It was just meh.
