That was the theory, but it's not the way things are anymore.
A whole load of stuff is being released Intel-only now. The newest PowerPC machines are now two years old, so if you're releasing something that needs a this-generation machine to run reasonably, why bother?
This proportion is only going to grow over time. And it will probably be riddled with endian bugs, alignment assumptions, and x86-only toolchains. Going back to PowerPC would be at least as traumatic as the initial switch.
