According to an article on 8bitfix.com, it seems the recent delay may be a pro-active move on Sony's part to keep pirates from being able to play the game on modified systems.
Sony recently announced Gran Turismo 5 would be delayed till later this holiday season. Initially, no details were revealed and the only response from Polyphony Digital cited "kinks" in the system.
"I'm really sorry. Everyone, it's inexcusable," Yamauchi wrote on his Twitter account (translation via Kotaku). He also gave at least a brief explanation for why the game suffered yet another delay, saying that, "it's because time and labor were spent ironing the kinks out of [the game's] complex system."
However, a more believable explanation from user Maximus on the Blu Ray Forum sheds some light on the real issue.
Like I said it is manufacturing issues. I had it confirmed today.
The problem arose when SCE mandated SDK 350 on all games releasing after after October, GT5 was about to go gold running on SDK 341, but it has been delayed by around a week so that they can update to SDK 350. This has caused a big headache for the manufacturing side, given how big this game is missing the gold date by even a week can cause a months worth of delay as slots are already taken up at this time of year for Blu-ray movies and such. So Sony had to find a 3 week slot big enough to make 7m+ copies of this and get them shipped out.
If you want to blame anyone, I would direct it at the pirates and hackers, SCE never had any real SDK restrictions before firmware 3.41 was compromised.
This forces all PS3 owners to upgrade to 3.50 firmware which fixes the PS3 Jailbreak hack. No word on whether or not the hacking community will be able to get around this. Be sure though, if there's a will, there's a way.
While the 360 and Wii have been plagued with piracy problems, this move by Sony should make owners think twice about "jailbreaking" their PS3s.
