If GT5 comes with rewind, so be it. My personal oppinion is that the biggest heresy ever commited to a racing game was the inclusion a B-Spec in GT4, in such a way that instead of a new and refreshing "manager mode" (completely separated from your career as a racing driver), you basically had the console doing the driving, getting your cars and prizes, completing your championships, etc.
Thank God the License Tests and the Missions were "B-Spec Free" ...
Damn, I hate it when people are right
