Game developers are not at all open to experimentation, only adopting new languages or architectures when vendors force them to move forward.

PS3 with Cell would have been a failure had Sony not eventually caved in, and released a PS3 SDK that made most of the work Sony was initially expecting devs to do, regarding low level programming.

That work became PhyreEngine.
