If the PC stays x86 I think a PS4 will have a CPU processing advantage over the PC, like is currently still the case with the PS3. I think both PS4 and new PCs by then will come with (faster) Blu-Ray drives, so this current PS3 technology advantage will go away.
I think the PS4 may not arrive yet by 2012, although I expect a Wii and 360 successor to become available before that. The PS4 will likely have a much easier entry on the market, launching at a cheaper entry pricing, much more mature and efficient game engines due to PS3 adaptations and will have a very mature XMB OS with Playstation Home (taking your PS3 customized Home and charaters with you onto the PS4), PS1/PS2 software emulation and full PS3 compatibility out of the box.
