Doesn't surprise me really.
1) Most of the people who have bought 360's now know what to expect from the console in terms of exclusives: new XBLA titles, and some bold shooters. Sprinkled with a bit of Fable.
2) A big budget game this late in the cycle doesn't make sense because...
3) ... because Microsoft plans on unveiling a new system within the next two years. They will focus their "gaming" efforts as launch titles for the 720. You don't want to dwarf 720 sales by having a lot of AAA exclusives come out for a system prior to your new one.
4) Microsoft plans to appeal to the casual buyers *again* because there are people out there that want to use it as a multimedia device but are looking for more options.
I don't think MS will put more effort into games before releasing the 720 outside of what they already announced. By working on media features that lays the groundwork for the 720.
It's just that simple.
