Just quickly about the DSM (of course what you say about the very long revision process is completely true): it's not likely they will do away with personality disorders as such, exactly, but the model used to describe them, probably becoming more dimensional and less/not categorical. It is likely or not unlikely, because there is a Section III in the DSM where tentative proposals by the different working groups are described, for (possible) future use, and a more dimensional approach to personality problems is in there. The only reason it was not in the "normative" part of the DSM is that clinicians thought that it was difficult to work with (which could just be clinging to what you know). I personally think it can be very helpful in clinical practice, where now it is sometimes rather/almost meaningless which exact personality disorder is diagnosed for psychotherapy.

I will reply to the rest later: just don't have the time to read and formulate a response now.
