ABSOLUTELY, POSITIVELY, not.

Of course not. If you notice, the 360 is still a little small in the amount of available games. Not to mention that game with the highest graphics available at the moment (Crysis, this is in my opinion though) is originally planned for the P.C. It may come to 360 but we are not 100% sure on that. Look it up at IGN, and watch some of the videos, really cool.
Many games are planned for other console releases, just because they are coming out soon. Think, when the Xbox was released many games were put on there to get more copies bought. This happens with most console releases. The PS3 already has over thirty planned release games. Once these consoles are just regular consoles and there are no new ones in sight, the P.C. is looked upon as it always is (in my view it is looked upon as #1 for game consoles).
