@Mitsuhide: wanna give me an example of how 360 sales are falling? Cuz last I checked, they were still better than they were last year, which was a pretty good year.
PS3 and 360 will both be relevant no matter what, but we'll have to wait a few weeks and see if the 360 can sustain its' current level of sales (selling on parity with PS3, a few k higher or lower each week)
