Oh, believe me, I fully understand why it makes no financial sense. I mean, in reality instead of waiting 6 months, they should just wait 14 and do a Nov. '10 release. They aren't REALLY going to lose fans. People say "screw them" now, but when the game hits, those same people's wallets will be $60 lighter. I guarantee.
I don't care either way seeing as I have a goal of getting 100%(with the exception of all gold on license test because I'm using a controller) on my old GT4 before GT5 is released. I'm at 54.7%.
