SOE's John Smedley has been busy blogging about their games, and he says this:
"...early next year we will have announcements about Planetside Next followed by a beta. I can say this - it's coming along awesome. I can also say that the first beta testers are going to be current Planetside subscribers. I've gotten a lot of email from current players offering to help test the game and we're going to take them up on it."
