I think we should spare it and make it part of TES VI: Elven Dominion.

Having a DLC which added some Akavir would be great, and far from impossible according to lore. They seem to come to Tamriel now and then, usually in an invasion force.

IMHO if we all of a sudden flew over to Akaviri in the next game I wouldn't complain but as well it would be a HUGE dramatic change. It would be interesting though. I mean think about it...... Monkey - Folk, Dragon - Cats, IMMORTAL Snake - People, and Snow Demons...... I mean like I said HUGE dramatic change. Tamerial is more .... lets call it fantasy realistic. I feel like it's almost a real world but the lands that Akaviri holds would be extreme conditions. Maybe Akaviri seems more intense because of its mystery (other than what can be read about it).

I predict that they'll be in TES X, because they'll need to pour half the GDP of the US into that title anyway to live up to the X on the end.

But, they'll need a sufficiently epic badguy... Nazi elves ain't it.
