while I have switched to PC version on my bootcamped Mac mini (looks like ps3 but with more people/mobs visible) due to issues with fates and select few ps3 issues, I have not had nearly as many issues on my original model PS3 that most people have observed.

Most people I know with many issues on PS3 have newer slim/superslim models, and most with minimal issues have to old fat boys, so it seems there may be some type of generational issues with the PS3, but soon ps4 and all be fixed.
