People have to get it into their heads that the major reason why games weren't ported to the Wii was the radically different architecture.

PS3 says hello.

PS3 has a GPU with similar functionality to the 360 or any PC GPU. Only the CPU is different, and even the Cell has a main core which is the same as a 360 CPU core, which can be used as a starting point (or both as the start and the end point, which is probably why some ports run like crap on the PS3).

The GPU design affects much more stuff than the CPU does, since artistic assets have to be reworked to look acceptable without shaders. A change in CPU design only affects the programmers.
