Bethesda has said the upcoming 1.4 patch for PS3 users will fix the lag and save glitch issues people have been experiencing although no promise the save glitch will be completely fixed for everyone.
After receiving a lot of save files from PS3 users to discover the problem, they found out that the bug isn't being caused by a single issue that would be easy to patch up but instead from multiple issues. To make things worse, each problem seems to be dependent on the user itself which means a patch that fixes one user's save file might not be able to fix a different person's save file.
