One of the biggest announcements, at least to my mind, didn't take place during a conference - Microsoft announced that it would be offering full game downloads for their system. I was sort of expecting Sony and Microsoft both announce something on this level, and Sony did in a way - the PSP Go! is a device that almost entirely removes Gamestop from the equation. Without a UMD slot, the only thing Gamestop gets to sell is the device itself - a contraption which is nothing less than a stake in their own heart. I'm sure they'll love that.
