It would indicate there is a problem with the game for sure for it to be delayed only a couple weeks or so from release. But if that is the case then in my opinion they made the right call. If the game needed work then work on it. So many titles are released early to simply cash in rather then be the best game they can be. Pro Evo Soccer is a good example of it.
But that said the game was teased in like 2005, that is such a longtime to work on a game. If the game is not the best racing simulator of all time then they have come up short. The cost to make the game will be massive. Paying all those staff over 5 years as'well as the actual developing costs mean that Sony will have spent a fortune on making this game. It is 100% the right thing to delay the game if it is not at that high bar level.
