Anet has announced that the next BWE will start at noon PST on the 8th of June.
Existing Beta characters have not been deleted, so those that have played deep into the game will have the opportunity to try out the Ascalonian Catacombs dungeon.
What I liked most in their announcement was this paragraph.
We have listened intently to all of your feedback from our first Beta Weekend Event, and we’ve made great strides toward resolving many of the issues you’ve helped us identify. These include party movement into overflow servers, chat functionality, key bindings, server stability, performance, and many more that we will detail in the near future.
Considering I plan to play almost exclusively with my wife and son the party movement is a big deal. I don’t mind the idea of overflow servers so long as my whole group gets put in the same overflow. I will also be interested to see what they have added for chat functionality. There where only a few chat channels available during the first BWE, and it left a lot to be desired.
Right now I am very excited and am counting down the days already.
