Post show interviews
You didn’t miss anything from that interview. They repeated everything they had said in the presentation and were even explaining some of the basic features of GW2 (not HoT). The only little piece of interesting information is that a playable demo of HoT will be at PAX East in 6 weeks.
I picked that up from woodenpotatoes, but that is right about all I can find about the interview. But if the rest is unimportant, I won’t bother searching for them anymore.
ManVSGame conducted the interview, though it doesn’t seem to be on his channel either.
As Zalladi said though, you didn’t miss anything. It was more frustrating to watch than anything, because the interviewer obviously hadn’t played GW2 since launch.
