Sounds like a lot of Mac ports... just ask Cash what he thinks of Driver for Mac.
Personally, I couldn't agree more with you (or Cash, although not with the way he phrases his frustration). Companies that port a title 12+ months later and then experience poor sales, which they blame on the platform, have no one to blame but themselves.
I don't think Hondas would sell so well in the US if they sold one-year-old or two-year-old models here but current models everywhere else.
