Guild Wars 2 Enters Closed Beta on Friday, Reddit Q&A

In the course of a Q&A on Reddit about Guild Wars 2 (available now here in Google Doc form) an ArenaNet developer has revealed that the closed beta of the title is officially starting this Friday, but unfortunately, due to the Non-Disclosure Agreement, it's very unlikely that those not involved will get any new information out of it:
We will officially enter Closed Beta Testing this Friday. It will be marked with an increase in our pool of testers. To clarify, this phase of testing is still under NDA and is not open to the public.

Based on the feedback we get from our current Closed Beta Testing, we will determine the next phases of our beta program in which we will open beta access to more people.

Since there is plenty of other information to get from the Q&A, I'm going to quote another couple of questions and answers from it:
What's going to make GW2 PvE even better than GW1 PvE?

Everything. ...our PvE is so much more dynamic this time around. We've put a lot of thought into how [skills] are going to play in PvE as well, moving, dodging, etc. . I think Dynamic events are going to change the way people expect to experience content in an MMO. No more kill stealing, no being on the wrong step of a quest from your buddies, no waiting in line for someone to complete an escort or kill a boss so you can do it. The world being dynamic around you and feeling like you need to get in there, help take the garrison back and do it not just for yourself but for everyone on your server working together.

...

what will the endgame look like?

Endgame is such a dirty word. We want our game to be the endgame. We don't like the idea of a game that changes when you hit max level. As you level up you can play events, dungeons, WvW, or at anytime take a break and do some competitive PvP, and then hit a button and go back to PvE stuff.

...

Favorite thing in GW2?

Dynamic Events. It will be nice to finally play an MMO with content that makes sense for the genre.
