Lots of good info, like no free-to-play, Warhound won't come back, some info on Blizzard All Stars, the reasoning behind the new units in HotS, etc. The interview is a few weeks old (it is so time consuming to subtitle half an hour of video!), so some of the promised changes for HotS are already live in the Beta.
Enjoy it on our website (it is all in english, just ignore the subtitles):
Hope you like it!
