Just finally got around to watching the show last night. I can easily say Halo 4 saved the E3 from being pretty meh.
It started off so very awesome with Halo 4 and just went downhill after that. Xbox Smart Glass is very awesome IMO. And more apps makes me happy (especially NFL games in ESPN finally). I didn't like how they only did very short trailers for most every game I had an interest in and the 3 new exclusives they showed either looked horrible or has such short trailers that you had no idea what the game was about other then what it's name is.
So all in all, an awesome start and a few cool things but everything else was pretty mehish.
