Guild Wars 2 Alpha and Beta Testing in 2011

According to a small update to the official Guild Wars 2 FAQ, ArenaNet intends to run closed alpha and beta testing sessions of the highly anticipated MMORPG sequel later this year. This isn't an indication that the game will actually ship in 2011, but if testing goes well, it certainly wouldn't be impossible:
When will there be a beta?

We will be conducting small closed alpha and beta tests in 2011. The feedback from these tests will determine when we will do public beta tests and ship the game. Guild Wars 2 is a very large and ambitious game, and Guild Wars players rightfully have very high expectations. We want players to be absolutely blown away by the game the first time they experience it.
Thanks, Massively.
