I like having competition in the market, but I despise Sony in general, even though I own most of the systems they've put out (PS1, PS2 x2, PSP, with plans for the other two).
Personally, I wouldn't mind if Sony was forced out of the videogame race. Competition is good. A three-console competition isn't so much. In the third, fourth, and fifth generations, we essentially only had two-console competition (Sega had gone niche with the Saturn, albeit accidentally), and I think gaming benefited a lot from it. Three consoles is making things too expensive for developers and gamers alike.
