I suspect GPU physics is only temporary. When a CPU comes out that can handle it just fine they'll probably move back to the CPU to keep GPU performance up. I'd imagine that the successor to Nehalem with 512 bit vector instructions could do enough physics calculations on a single core, with easier programming than on a GPU. Thats two years away though, with larrabee they might just have a single x86 code for physics that can run on either the CPU or a larrabee GPU as needed.
