My biggest concern with what i heard from the livestream, is that the new 64 bit server, (not the temp one they are testing) is that they want it to be of equal footing to everyone. The problem with that statement, is that you realize that it means that character transfers won't happen, because it won't matter if its 3 months down the road, or 1 year later, the moment the completionists arrive, the "equal footing" goes away.
I will not throw away 15+ years of playing and building characters, to start new, no matter what it does to the lag.
