I don't think MS is going to let 2008 go as easy as you guys may think. The way I look at it, MS is saving a lot for next year. Since they have a good year this year and considering their track record of excellent software sales, they may probably have bought out some PS3 exclusives again. Not the big 3 of course, but they would hurt Sony again seriously just like what happened this year.
Next year we'll see more lost exclusives for Sony and more new IPs going to be released for Xbox 360. The only question now is whether how those will fare compared to the big three juggernauts Sony is set to unleash next year.
Just my .02
