I wouldn't say as much as "excel", though some can be quite good to use. But I disagree about MMOs, which are usually FPS/RPGs, and some of them can even be playable on the net from a console. It depends a lot on the stuff being done.
Anyways, let's hope consoles don't kill the PC, I refuse to take on consoles, or having to develop my games for a console. PCs have far many more advantages.
Cheers
