This isn't a "Sony" issue. This is a Bethesda issue that's come to entangle Sony. As they have already said, "[They] support all of their developers and try to help them overcome these types of issues."
Regardless, the truth is that they can't do anything if gamesas's coders are incapable of getting it to work. It's not like Sony sent their coders to gamesas. They're most likely just chatting on the phone about the issues and the Sony experts are probably quietly judging the Gamebryo Engine/Creation Engine in the back of their minds while wondering how in the world gamesas's PS3 Platform Specialists are even employed at this point.
According to some, this is a Sony issue, in part for having half the RAM of the 360, and infinitely less than practically any actual PC, and in part for being so hard to develop for. And you can hear that from a lot of developers.
