@CGI - I think the reason this debate will never end is down to the more extreme fanbase of each console.
On the PS3 front they were pretty much mocked for 18 months after the console launched at paying for a system worse than the 360 technically (most games supported this unfortunately). Now the PS3 has a few titles that in a Sony fans eyes look better than the 360 games they've become just as petty and annoying with the shouts of how powerful their system suddenly is now. The 360 fanbase then comeback with multiplats look far better though on the 360 hence it must be because Sony chucked money and people at devs for them to optimise a few games not down to hardware.
All of these sorts of discussion are irrelevant though imo as when I look at the 360 and PS3 games I don't see any gulf in performance at all. Last generation the gap between the PS2 and Xbox was huge, this generation the difference is blatantly tiny.
To the guys going hammer and tongs at each other in here, you lose credibility for me when you start picking apart developer quotes as "evidence". MikeB gets criticized for misusing developer quotes constantly so I owe it to my sense of fairplay to say I think the rest of you are just as bad using them as some sort of proof. Too many quotes are taken out of context and very often they can be misquoted to start with.
