PS3 Graphics

[Jinko]

I doubt PS3 will have any AA tbh, shadows will be minimal at best.

If you can afford it you would be best going with a PC upgrade.

What worries me is that they will dumb down the engine somehow to shoehorn it into the PS3 and the PC experience will suffer. That the game looks so wonderful is a big reason why I like it so much.

It's unlikely to be like that, a decent game engine will be fully scalable, PS3 version will no doubt use lower res textures and assets and high LoD settings.
