(That was in reply to someone speculating that a release date would be announced on the 10th or the 11th due to pre-purchases starting)No, we won't. It's not like we have a secret release date and we're not telling you. We meant what we said: we'll release the game when it's ready. And beta testing is where we find out if it's ready.
Personally I'm not especially happy about this, though I've been critical from the start with Anet using beta incentives with pre-purchases rather than pre-orders (unlike almost every other game company) even though there is no official release date. However, I'm hesitantly optimistic that we should definitely have a release date by the end of April after the first BWE (as long as it goes well) so I'm happy in that regard.
