raspunsul oficial din partea lui Yamauchi: Kazunori Yamauchi Briefly Explains Gran Turismo 5's Delay (andriasang.com, 10.14.2010)

Returning to Twitter for the first time since September 22, Yamauchi apologized to fans today and explained that the reason for the delay was that it was taking some time to finalize some of the game's more complicated systems. Apologizing again (two apologies in the same Tweet!), he asked that players wait a bit more.

Yamauchi quickly followed up this apology with some good news for those worrying that this is actually a stealth delay to 2011. A follower pleaded with him to get the game out by the end of the year. "I believe we won't keep you waiting until then," replied Yamauchi.
