Fmulder unearthed a nice quality video of Jay Wilson presenting the Demon Hunter at the Gstar show in Seoul Korea last winter. It’s basically the same as the panel reveal from last year’s Blizzcon, with the evolution of the Demon Hunter’s design, coverage of her skills and lots of gameplay footage. There’s video and discussion of other new characters skills and runestone effects as well.
I didn’t compare frame by frame, but some of the gameplay footage looked different to me. It’s an entertaining presentation at least, though 45m long, since everything Jay says is then translated into Korean, plus the text of the slides is all in Hangul.
