The 360 is as good as dead. M$ is probably gonna release a new console either next year or in 2010.
And it's quite foolish to say Sony gave up market share... it's been just over a year for the ps3, and not even a year for europe. Even though it's been said over and over, 2008 willl be the year the ps3 starts to gain considerable market share.
I'm predicting that the ps3 will overlap the next generation, and release the ps4 in the generation after xbox 3.
