Do you guys think it'll be a huge city in TESO?

Nope I don't specially considering it was already stated it won't be in the initial game, now an expansion may come later with it added and it will likely be a bigger city than what is in skyrim.

right, it wont be in the game to begine with, but we might se it as a DLC, and i do belive it to be a bitt larger than in Tes V
