The Blizzcon vids I've seen so far make this look and sound pretty groovy. Same game running underneath, lovely new graphics on top, a few quality-of-life improvements (I like the auto-gold-pickup and also that it's optional so old-schoolers don't scream). Shared stash makes sense, and was justified by the fact that everyone does it anyway with mule characters, might as well make it legit and simpler. Single Player!! At least I'm assuming that that's what "offline play" is. One of the vids said that you log into Battle.net (probably just to verify your license blah blah blah) but then it just runs on your PC. Or console.
