Id hazard a guess at a definite 2010 release, the game seems ready , and all they're doing now is testing and in-house playthroughs, they'll post up the Necromancer profession officially like the others, then i think they'll start the run up to release.
November would be a good bet.
oH, and during the demo this morning (even though my german si not great by any means) i think the mc accidentally referenced a 'Scout' class. Don't hold me to that though.
