Well, one thing HAS obv changed for PvP

Respec allows to keep your character, even when you are lucky enough to find a certain rare/craft etc. that would usually make you re-create the whole char (assume for example a 30 STR Circ instead of a 27 STR one on an ES-Sorc)... also, powered Hydras might actually WORK as better helpers for Fire Sorcs... the rest of PvP does not seem like it will change a lot ofc...
UNLESS ofc there are more changes to come which were not worth mentioning or implementing in the test realm...
what I don't get is the hint that a new series of tests awaits from Den of Evil to WSK when Den isn't actuall a part of it... at least so far...
