It does say divine. That kind of sucks though because I thought that the sorcerer was going have the Elemental power source. sigh.
I don't think you should be so disheartened. The specualtion for a while now has been that Sorcerer would in fact be in the Primal power source.
Also, dont forget the leaked 8 first initials of the new classes of PH2...
D, B, B, S, I, W, T, something. 3 of which are brand spanking new never before seen classes. Which means 5 of them are classes from previous editions.
My picks are...
Druid - Primal hybrid
Bard - Arcane Leader (but he may show up in DDI before the PH2)
Barbarian - Primal Defender
Illusionist - Arcane Controller
Sorcerer - Primal Controller
