I have heard stuff about the AI. Well, Sony said that the AI is going to be a lot more adavanced than previously, and they said that like every NPC will have like their own programmed intelligence. So say you're playing a war game, some characters will choose to run, and some will stay and fight. That's the example they gave. Microsoft then said that the 360's AI will definitley compete with that. So as for AI IMO, it looks good. And for the HD memory card thing, yeah you still can which is cool for when you wanna take a file with you to your friends or something, that way you don't have to bring your whole 360.
