But anyway I'm guessing Kaz is going to blame it being dropped on short development cycles (6 years, the horror!)
I think it could link in with the announcement to be made at E3, plus the track logos found on website. Mass time-trialing/hot-lapping anyone? It could work in their favour to bring in something like Autolog in NFS for it, effectively bringing leaderboards to GT5.
A boy can dream...
