Don't worry. The cycle of gaming will hit them.
1980-1995: Console gaming
1995-2005: PC gaming
2005-2015(?): Console gaming
2015-2030: PC gaming
The return of the PC for gaming is near. The Wii U sounds unsatisfactory (poor marketing excuse for it), M$ and Phony haven't shown anything new. I can't wait for the cycle to appear again.
