If you don't understand why somebody would want to play an RvR only game for years, then CU probably isn't for you. Many CU backers also can't understand why anyone would want to play a PvE heavy game for years. News flash: different players have different preferences and like different types of games.
Fortunately there were more than enough players who did find the idea of an RvR only game appealing that CU funded. And if it actually is a good RvR only game at launch, then it won't have any trouble keeping enough of those players subscribing to remain open for years too.
I think ignoring the game until much later in beta is a good idea for backers or potential future players who aren't really interested in actually testing the game as it develops. Launch won't be happening anytime soon and when Beta 1 starts is still a big question mark despite the optimism that comes from CSE every Friday.
No announcement of a date nor even an announcement of a date to announce a date yet. Work on getting the game to beta continues at the same steady, methodical pace as always. When there is something to announce CSE will let everybody know.
