When talking about the best this year, I think Microsoft is really a non-factor. They know where they're sitting and they know where they're sitting is a good place. They aren't going to completely blow the show but they have no really need for huge megatons. They just need to not disappoint and they'll be fine.
The real fun is going to be what Sony and Nintendo does since Sony is riding on some good momentum and really needs to keep and Nintendo needs to make up for their abysmal showing last year.
Personally, I think Sony will do something to screw themselves because that's just been what they've really been good at doing this gen. Every time they build some really positive momentum they do something to knock themselves back down again.
Nintendo knows how horrible they were last year, they have a lot of things in the works, and I think they're really going to bring it.
