I have my first psychologist's appointment for AS on Monday to see about getting a diagnosis. I spoke with her today and she said she could offer me a diagnosis based on the DSM IV criteria, but that she didn't know how valid it would be, due to the criteria in the DSM for AS being so outdated. So, I was wondering, should I wait to get a diagnosis, or is the current DSM criteria really that different from the proposed criteria in the DSM V?

It's not outdated, it's just not applied very uniformly, and when it was first introduced to the DSM-IV, there were no actual assessment tests for it. However for the larger part of history there were not assessment tests for much of anything. A diagnosis of any psychiatric, neuropsychiatric, or psychological disorder previously just entailed the doctor saying they thought you had it.
These days, however, assessment tests have become rather standard in diagnosing and those who do not have a diagnosis via such modern methods run the risk of (or have the advantage of) having their diagnosis doubted, and as criteria and testing procedures change, one might find themselves being put in the position of constantly having to "prove" their diagnosis through expensive, repetitive testing.
As silly as that can get, I have to say that there are other things that can mimic AS and it's important (at least from a scientific standpoint) to rule out these conditions. The DSM-IV criteria alone can't do that.
