Not sure if you're just teasing.. Don't care. 

Solly/Vivi.
Edit: It's sort of like a Monet. Go stand on the other side of the room and look at it. 
Yeah, I saved the file and zoomed waaaaay in. Definitely Solas, but not sure if that's Vivienne or a human at all--can't figure out where the head would be.
Solas, however, is definite and not just because of the bald head. It's that whole "he's wearing that fur drapery over his right side" thing, if you extreme-zoom to see it. But the other figure, well, if that's a head it's too big. Almost looks like the figure is bending so that the head is pointing toward us, while the staff is pointing outward, but that's such a strange pose I can't imagine that being right. They are too close together for Vivienne's head to be that big--Rhodes is skilled enough he wouldn't make that kind of mistake with perspective. So I think either I am looking at it totally wrong or that may not be a person he's beside at all...
Still, interesting that he was chosen to be on the cover art over some of the others. It bolsters my theory that he'll be extremely important, and extremely important companion characters are usually LIs. Not always though.
Edit: Okay, I think I see a figure now, but I can't say it looks like Vivienne even so. Definitely a mage, but that's not a horned hat--it looks like a tiny arm is splayed one direction, with the head up the other, and then the staff coming from the other arm. Could be her, and in fact I'd say more likely her than Dramatic Hands, but I have no idea.
