Oh and throw in a "no new IP" talking point, which I dont remember last year being an issue when the other guy was touting a big "part 3"...
But it is really bad, though, in that regard. You almost have to hope that the staples reinvent themselves seriously, and to some extent that is happening. The gaming bits are seriously boring, even though some of them make a lot of sense (Forza Horizon makes sense, and could potentially grab a lot of NFS fans that hovered between Forza and NFS and were happy with neither). Halo 4 I think is very promising in that despite being by a new developer, it dares to be fresh, certainly got me interested. But man, all this shooting. And then I'm not really seeing much diversity even in XBLA games - so many of them tend to target a similar type of audience, for which I think the Southpark game is perfect.
I'm glad they are improving the searching in the XNE, but seriously, that thing needs a major overhaul. Like the Giant Bomb guys have said, allow for a bit of profiling to you can give preference to certain types of content, like ... well ... games. They don't just need to post Apps, they need to App Store it up with all manner of recommendations, rankings, sorting options, top lists and so forth. That will help all genres, but certainly also smaller games.
Overall, with a very few genres excepted, I think a game should not have more than two sequels on the same platform. Make something new after that, please, or reinvent the game so much that you get a Mario type effect - IP is the same, but the gameplay can change dramatically at times.
I really wonder what the other two big guns will have on show.
I do really like smartglass though (won't be long before people will call it smartass or something like that I'm sure), and I wonder if there is room there for genuinely different styles of control methods. There is a lot of potential for it in multi-media interaction as well as games I think, but they need to show it. It's still relatively early days, but a good test will be once the Nintendo conference is over, which will be 100% Wii U games, how many of those experiences can be fairly comfortably matched with smartglass.
