The last couple of pages of this three have been fun. GT5 was a mess at launch because Sony practically forced PD to release the game. That being said, at launch, it was kinda shit. Let's just make sure that is understood. Second, PD has done a fantastic job updating the game to this point. There is a lot more they could fix, but overall the game is in a decent state.
I agree with some people here PD needs to either expand internally or outsource. Kaz has a vision that is beyond the capacity of his studio. GT5 bit off more than it could chew. The game and its fans suffered for this. Hopefully the rumoured more simple architecture of the PS4 can help mitigate this. These two things together are why PD need to release GT6 on the PS4. We can still get more GT5 content through DLC, but PD need to focus on laying the foundation for the next generation. This one is lost. They parched it up the best they could, but it is time to move on so this never happens again. GT6 on PS3 can only be more content and new features. Is this really better than continued GT5 support? Can this not be achieved through continued GT5 support? Not to mention, is it worth delaying a next gen GT even further? No.
