Rockstar takes back their statement of blaming or co-blaming the newest PSN update after numerous complaints involving the Xbox 360 version sort of hurt the claim of the game not causing the problem.
Some reports are saying Sony might have forced Rockstar to re-issue their statement due to Sony not wanting more bad publicity and once it was found out Xbox 360 were also suffering the same issue at around the same rate.
They are currently working on solving the problem with an update but it still has been shown to be more of a problem with older PS3/Xbox 360 models than the Slims or Elites. Current solution for Xbox 360 owners is to clear the cache to see if it helps to solve thr problem until the patch is ready.
