They're separating the servers into regions, there's no international servers,
Incorrect. All servers are STILL INTERNATIONAL. The effect causing regionality is servers will have regions associated with them, based on their physical location. *ANY* player can still choose to be on *ANY* server.

Where did you read that?
Right here:
Players will have the freedom of selecting any world they prefer.
I swear, did you people in the thread now not read the original post. ANYONE CAN STILL CHOOSE ANY SERVER.
