$600. No thanks.
I haven't seen anything on the PS3 that justifies the price, or makes me excited for it. Yeah MGS4 looks awesome, but I'm far more excited about Gears of War, Lost Planet, Blue Dragon, and Resident Evil 5.
The PS3 doesn't have any games that compete with stuff like Gears or Lost Planet right now. I'm not interested in more jappy fappy RPG crap. I missed all that stuff on the PS2, so I'd probably buy a PS2 if I wanted to play RPGs.
