The Xenos chip is actually made by ATI, not Nvidia.

That's a little misleading because it's a known fact that games developed using the 360 as the lead platform do not port well to the PS3.  Up until now pretty much all multiplatform games have used the 360 as the lead platform.  I think we'll have a better comparison when FFXIII comes out, as that's the 1st high-profile multi-platform game I'm aware of that is using the PS3 as the lead platform.

Also...a few devs have said that if you lead on PS3...The 360 will be able to give the same performance....But not vice versa...Funny right?

but that not because power, it's because 360 gpu and cpu get benefits from good programming practices, you are forced to do to get perfomances from the cell and even so many developers only use the PPE, 2 spu and RSX at most.

 it benefits games like burnout paradise that was one of the first 60fps games on the 360.

with a lazy programmer when you give them engine they never rewrite libraries, let alone go on low level programing,  to make use of the cell spus.

epic done a good job making ue3 better, batman asylum, and UT3 run great on the ps3, and look the same or even better 360 version.

same can be said about RE 5.

but this practices  have slowed, graphics lead we being seeing since it takes extra effort, to get better graphics and developers are happy to the outcome they get.

but now you see games from sony, like killzone 2 uncharted 2, GT5 with better graphics than the competition and even so progressing even more.

Lol??  What does it smell like?  New car smell? Freshly baked chocolate chip cookies? Gardens?  And how can something tase more powerfull?

But personally, I feel we are only just starting to unlock the potential of 360. With games like Forza 3, Splinter Cell, Alan Wake and even 3rd party games like Lost Planet 2, FF13. Personally no game on PS3 beats Forza 3 or Alan Wake. So it's really what art you prefer. As the PS3 and 360 are so closely matched. The best tech in a game yet is ID Tech 5 RAGE. And that is running better on 360.
