Except for the development and portability concerns, why would any console gamer care about what architecture is inside the consoles? I have friends who would never ever touch a PC to play games. They just don't like PC Gaming and its hurdles. I personally do not play the latest games on PC either, it is just too much drama. I don't have time for it. The console gaming is easy, convenient, trouble-free, straightforward, stable etc... Has many advantages over the PC games (as well as disadvantages of course).
The fact that they have an x86 architecture is irrelevant for PC vs Console for the most part.
