Personally, I noticed this stuff when playing both demos side by side. \

360 one seemed alot darker than the PS3 one

PS3 Apprentice model looked rather blurry adn undetailed, also their were AA problems on his model.

I did notice more AA issues with the Level on PS3.

There was lack of facial shadowing on the PS3 Apprentice.

Now, hopefully this was a early build of the game adn these issues have been fixed, however im still pissed PS3 cant get alot of equal ports.

Well I don't own a PS3 so I can't compare but I didn't notice any shadowing on the apprentices face in the 360 version.
I doubt this is an early build of the game. It was probably taken from a build some time in the last month or so seeing as how the game is going to be released in not too long.

The 360 demo didn't have those issues (for me at least) but I could notice the lack of AA on some objects and wall....
