Also, I wonder if emulation of these newer systems, which is a special kind of retrocompability, will be feasible. It seems that the PS3 and XBox360 are already hard to emulate, not only because of complex hardware but because of all the annoying (from an emulator developer's point of view) non-gaming capabilities interfering with the third party software (achievements, online capabilities, etc). Another sad consequence of the consoles who want to be more than consoles. The Wii, on the other hand, has been emulated for a while, despite its unusual controllers.
