Welcome to the Forums. Hope you enjoy your stay.
I am sure the Developers are working hard to alleviate the issues that occured on the PS3. We have a thread specifically for that and ask that you use that for any PS3 issues you want to be resolved. This way the Devs don't have to look in every thread for what to address.

Since I think this was the purpose of your thread, I will close this one so that you can post your concerns in that thread. Or other threads that you may want to participate in.
