The statements pretty much cover the spread from good to bad. The most interesting anonymous source talks about several studios who had various levels of experience with the UE3. The key thing is that the source doesn't believe the problems were "intentionally malicious," but a product of Epic being stretched thin because of their own product development. Interestingly, this is given even more credence by Sony swooping in and lending support to Epic in getting the UE3 working properly with PS3. The question is slowly turning into what did Epic deliver to these developers through their license? How much extra work did these developers have to put into the engine to get it functional? Obviously, Sony felt the need to help out. The Unreal Engine 3 tree is going to continue shaking and we're sure to see more stories fall out very soon. Hopefully, with developers who know what they're talking about and are willing to go on the record.
