Far too early to tell. Remember how the 360 caned the PS3 in the early years only for it to make a stunning comeback. MS could iron out the kinks and release some better development tools. The cynic in me says game over as far as games go in Sonys favour not least because it has better tech but let's not forget the PS2 was incredibly successful and yet was most likely probably the weakest of the consoles.
