Guys... it seems like the GT5 load time issues are caused largely in part by the constant internet connection that is being used. Apparently if you disable internet your load times should drop significantly. We will also be seeing a patch for this soon. I can't try yet cuz my PS3 is in the process of being backed up from my phat to the slim.

Let me know if you guys see any improvements.
