I think its fair to say that developers learn from their past experiences. With ncsoft, that being guild wars, the servers were also seperated but you could pick which server you wanted to play on. At the start you could only switch a couple of times before you were stuck on one server. Some people had multiiple accounts so they could play both as access to the underworld and fissure of woe were limited to whichever server held favour from Hall of Heros. The servers were later fully integrated allowing anyone to play on any server at will. I'm sure this will work similarly, you'll be able to pick and they'll mixup later, hopefully they won't take aslong as in GW. Theres no reason why you can't create 2 guilds and have a NA and EU division, or even for each faction. My GW guild has 5 Luxon and 6 kurzick guilds and members from all over the world.
