Diablo 3 - Gameplay Video Preview @ G4
 

A preview for this game can be found at G4. The gameplay preview is about 2 minutes long and it features art director Christian Lichtner talking about what he's doing in these late stages of the game's development. He's also talking about how the team has tried to keep the dark atmosphere of the first two games.
More information.

Did he talk about his internet connection dropping while he played and getting kicked off the server? How about Blizzard's testing with dial-up connections?

Can I say that the title of this newsbit is a bit misleading? Nice to have a short interview with the people behind a game, they just look like normal human beings :)

edit: typo corrected.
