I think this is the first major multiplatform title where the PS3 version is better.
I suspect Sfags are creaming their panties right now and inventing revisionist history suggesting it has always been the case (PS3 having superior multiplatform versions)
Ah well.
I don't think anyone is stupid enough to do that.
There are already plenty of titles that demonstrate the PS3 as a very capable machine, but it is most definitely less developer friendly and demands a non-traditional approach to get the best results. This does make it seem as if the engine for XIII was tailored for the PS3 and not really a multiplatform engine as they tried to lead us to believe.
It's very bizarre that resolution was sliced, though, as that is one area I'd expect the stronger 360 GPU to pull ahead.
This seems like a similar case as Bayonetta. There was NO reason why the PS3 could not have run Bayo perfectly, but the people responsible for porting simply did a poor job. I suspect a B-team was in charge of this 360 port and here we are. It's simply rare to see any game tailored for PS3 first and then ported to 360. It's almost always the other way around.
While it wasn't all that amazing looking, I do have to say that Visceral Games did a great job with Dante's Inferno. It remains quite possibly the most accurate multiplatform game we've seen to date. There is no difference between the two versions. It is basically 99.9% identical. Dead Space was just about the same as well. They know what's up.
Still, regarding XIII, the casuals won't give a shit. While visiting a friend recently, I was amazed when he fired up his 360 on his HDTV only to see that it was running in 480p 4:3 stretched mode. >_< I've seen this so many times before that I'm now convinced that more people are playing their consoles in stretched SD 4:3 mode than in HD...
