One thing about making it first person is that it would probably make it like World of Warcraft. At least from what I've seen. I'm sure they could easily do it. The difference would be that you fight different monsters and have different skills. And I guess you would most likely have different weapons, probably more of a variety though. That might be kinda cool if you could collect some of the items from the first two Diablos. Also you would be able to see the townspeople face to face (imagine talking to Cain face to face). If the game does come out, that would certainly be a possibility. The only problem is the plot, but it's Blizzard so I'm sure they can make something up.
