from a good source of an employee of rockstar games, the reason for the GTA delay is cause they need the extra power for GTA to run smoothly and at its current power of 222mhz and not the full 333mhz they couldnt get it to work right like they want it to. so they say that sony will release the patch to unlock the 222mhz hold and battery the same day or before or maybe a bundle package with GTA.. the source also said that sony might reveal info about it at E3 in a few weeks..
