Interesting bit from 1UP... apparently the HD version of Gran Turismo will be micro-transaction based, down to the individual car and track level.  A complete set would cost around $400 by the not-very-verified numbers listed in the article.  Obviously that's not really the model they are relying on but it will be interesting to see if this new console generation brings with it any really new business models.  $30 Platinum Hits on the Xbox 360 vs $20 isn't really new, just tuning to see what the market will bear.  XBLA is certainly a new (to the console) model.  But I don't think people are going to go for microtransactions when pushed to that extreme.  I guess we'll all find out...

Meanwhile, looks like the downloading of TGS trailers and demos is starting!  Can't wait to check out Lost Odyssey.  I'm totally a sucker for the way you can play along at home with this big conferences now.  I still want to get out to TGS in person someday though!
