It's been finished by people already, I'm waiting for D4.
Having said that, D2 cost me more hours of my life than any other game ever and I thank it for that. I didnt even touch Perfect Dark (which came out on the same day in the UK) for 2 weeks.
I won't be getting D3 due to the need for persistent connectivity, I'ma gonna go with Torchlight 2 instead.
