Here's all I could find. :-\
worldofwar.de: There is a rumor that players will only be able to play on the servers that are located next to them. For example European players would not be able to play on US servers. Can you confirm this?
Chris Sigaty: Yes, this is true. We will have the regions separated, for example US players on US servers and European players on European players. We will have regional support teams for online support, ingame support and offline support. This is because of language and time. We want to give the best support at primary playtime. If the European players play on US servers this cannot be granted. Another reason is that we want the Live Team to do regional events, let's say something like the Oktoberfest. Also the latency plays a certain role. However there will always be people who want to play on a server which is no located next to them because of their guild or something like that. At a certain point after release we will give those players the opportunity to play on those servers.
worldofwar.de: Can the EU play on US servers after the game hits the shelves in US until the game is released in EU?
Chris Sigaty: No. But if they have a opportunity to use a US billing method and have someone who lives in the US, we cannot stop them from buying an US account.
