My prediction: They'll announce Geomancer as the next healer/buffer/debuffer class. They will announce Hrothgar as male-only and Viera as female-only. The forums will detonate because everyone is expecting Dancer and we'll be getting two gender-locked races. I know these sound like far-fetched predictions, but to be fair.... it's just as likely as any other theory running since we have no evidence one way or another.

Real talk: The Geomancer is more wishful thinking on my end... *crossed fingers*
