First, we reported on German game site Buffed's interview with Jeff Kaplan that revealed more details of the new COT: Stratholme instance and an explanation of the Death Knight rune system. If you go to their page, scroll down past all that German and you'll find a video of the interview (in English!)
Later in the day, we covered Curse Gaming's own interview with Kaplan that announced Utgarde Pinnacle, gave more detail on the new Inscription profession, revealed the plan behind the increased pre-60 leveling curve and explored the dev's thoughts about giving the Hunter class some PvP love. Now Curse has put up a video of the interview.
Leipzig isn't over yet. Hopefully we'll have more revelations before the weekend is over.
