I have a Wii and a PS2 - which should I get this game for?

I would go with the PS2 version but it looks like it won't be coming out until January now I wonder why that is? Anyway I really hope the graphics on the PS2 version is better then the Wii's is, I bought Tomb Raider Underworld for the Wii and I was sooo dissapointed with the games graphics man Lara looks sooo ugly on the Wii I mean she looked so much better in Anniversary and there are quite a few other things: like the fact that layouts are really different from the other versions as well as how you solve the puzzles the fact there are no medipacks because Lara heals on her own which is ridiculous I mean you get shot a few times and are in the red and if you hide you automatically heal that kinda sucks as how easy it is to kill some of the enemies there is no mulit targeting no head shots and shooting while you are hanging from a ledge. I really hope the PS2 version is better then the Wii or I will be very sad
