MAG has potential and while it was cool to see anything on God of War 3, it's just a total cocktease that showed absolutely nothing. And while it was cool to see Little Big Planet again, this is the third E3 we've seen it at isn't it? I was really hoping for some "oh shit" moments with some brand new amazing looking games, but honestly nobody really had that this year which is disappointing.
Right now, I'd rank the conferences Microsoft > Sony >>>>>> Nintendo. Microsoft really didn't have anything new, but exclusive DLC for Fallout 3 and at least 2 pretty big exclusives I want this fall, plus the GTA4 DLC still put it ahead of the other two in my book. Plus, that FFXIII announcement was the closest thing to an "oh shit" moment thus far.
