I dont have very high hopes for a lot of patches.
Dont want to be a downer, but honestly i feel like its just a lot of talk and no action from PD.
It was the same when prologue was released. They made it sound like there would be coming lots of updates, and stuff, at one point they even claimed that it was somehow going to merge into the full GT 5.
I really hope I am wrong. And make no mistake i really love the game, it hasent left my PS3 since i got it. But somehow i cant help being a litle anoyed when i cant backup my savegame, or compete online with some sorts of reward, heck i cant even compare my lap times with my friends.
