I'm going to try to get the Collectors Edition from the Microsoft store for the Honda CR-Z, but I don't have much money. :smith:
I hope you can turn off the steering aid when you use a wheel. That's the only thing about the driving in Forza Motorsport that didn't appeal to me.
Even if they don't, I'll still be buying.
Why are there no Porsches?
Because EA holds the rights to feature Porsche in games, again. Instead, we get RUF, which is basically what Saleen is to Ford. Porsches that go faster with slightly different body panels, pretty much.

I think that Turn 10 now holds the rights to use Ferrari in Xbox games, so EA can't use it. 
Edited:
Are there actually any good xbox wheels that dont cost a fuckton? I know Microsoft dont allow any peripheral they dont approve of (cant make money off)
AFAIK, there's a Mad Catz wheel for like 100$, I've never used it though.
