That being said, I'm actually really curious why this game has had such a long development time? The wikipedia article says that initial development started in 2001. Granted, there may not have been much happening then, however, there is plenty of footage from 2008 of what appears to be a fully functional Diablo 3 (monsters, spells, etc. all look the same as the beta currently does)
So, it's just really bugging my curiousity, what's happened in the past 3-4 years? Diablo 3 seems to be taking the same amount of development time as a MMO game does, yet mechanically speaking I haven't seen that it's that much of a huge step over previous diablo titles (obviously there are huge improvements, like for example the physics in-game, but I haven't seen anything that warrants 3-4 years past a fully functional demo).
Just wondering =) and again, I'm honestly not upset at all, just really curious about what Blizz is up to!
