Rumor: New PS3 Firmware to fix GTA IV issues on 60 GB model
According to a poster named intimidtr3 on the US PlayStation Boards, 2K games Tech Support have said that Sony are looking into producing a new firmware just for the earlier version of the PS3 to fix the GTA IV issues.
To quote: Hello Xxxxx,
There is an issue with the launch edition of the PS3 and this game, the game was checked over and passed as 100% compatible with the current version of the PS3, of course the earlier version has custom chips which mean that it is a very different animal from the current PS3 on sale.
Sony are aware of this difference and are looking into producing a new firmware just for the earlier version of the PS3.
