From what I've heard, every companion in DAV will be canonically pansexual and romancable by the player regardless of race and gender. If they're going to eradicate heterosexuality, they might as well do away with monogamy too. I'm not even bi or pan, but the idea of a squadron of elite warriors who have orgies and defeat ancient elven gods is just so cool that I'd have to take that option. They've already lost the chud audience, so there should be nothing stopping them from doing it.
Ah yes, the Isabella, Leliana, Zevran, Warden foursome. Return to tradition
