Blizz has always designed around experience... in this case I think they decided going with the classic iso view would appeal to the nostalgia and more importantly allow the game to run on more hardware which is probably something they learned in spades with WoW. In a way they are like a high-end Zynga, always about the mechanics, always about the "feel"... keep you playing, keep you playing, keep you playing... because if yuo are playing you'll want the new Sword of Sadness from the auction house and put down the $3 real dollars for it instead of mining orbs for a week.
