Quote from Rick_Di 100% guarantee that if blizzard had made diablo 3 an isometric game built in the same style as d1+2, people would be complaining that blizzard can't make bold changes with art direction and that they are a 1 trick pony, or that the grimdark theme is so 1990's, why don't blizzard get out of the past? etc etc etc ad infinitum.
seems more like they're a 1 trick pony with the current art direction, as it's the same as the world of warcraft one...
