I agree, you can't really argue with that. Especially since the same games will come out on both, and you can buy 2 consoles for what would have been 1.
Plus, I doubt in this gen now, were going to see any differerence in the consoles power from the other one (the ps3 and Xbox 360 that is), unless they come out with a PC port, by which time, the PC will be slightly ahead, and the details will have to drop on the consoles release.
