We've contacted Bethesda to find out exactly what the PS3 patch contains. For the moment, the Xbox 360 patch, which is supposed to iron out some texture scaling issues and is also slated for release this week, is not yet available.
Update: Bethesda has released the official patch notes. No release date is given for the North American release of the PS3 patch, though the Bethesda Blog promises an update "as soon as it's up." The patch does indeed address the PS3 performance issues, among other tweaks. The Xbox 360 patch is expected to arrive this Wednesday. It should resolve the texture scaling problem and will also include the same tweaks as the PS3 patch.
Find the full notes after the break.
