I keep coming across these PS3 vs 360 arguments though which are of course pointless but almost more fascinating than the consoles themselves.
As it stands for me I reckon getting the PS3 will turn out to be a wise decision. But I can't help thinking I should've bought a 360 just to plug the yawning gap between PS2 ownership and PS3. Especially if I'd known in advance just how long I'd have to wait.
However I reckon I'd have been ultimately disappointed. Seems like the best MS has to offer are FPS with too short a story, though great to look at.
