I know this is related to the other thread, but a vote would put this to rest. If nobody wants to migrate to a server other than what they are on, then that's fine too.
PS - both Firetree and Spirestone are new PvP servers.
Me and another [H]'er are already on Drak'thul, which is only a few weeks old. My guild is kinda breaking up and I wouldn't mind starting a new one if you go to that server instead. I was in the hardguild on Stormscale back before I quit my shaman, and it was the best guild I've been in.
EDIT: Drak'thul is PVP too, I've got a 30 hunter, and Tylander has a 29 rogue, both on alliance.
