GM,
Follow your instinct. What does your heart tell you?

I would personally be afraid that it would sit idly most of the time, just like the Wii sometimes does. In my neutral Nintendo fanboyism, I'd pick a 360 over an PS3 at this moment. Many more cool games, rarely a difference in graphics. Even better, wait a few days to see if M$ also lowers the price of their consoles.
