There is no release date on the game at this time but i have been hearing news of the game to be released in late 2008 or early 2009, it makes sense for the end of 2008 around Christmas but then they would also have starcraft 2 and the new expansion for world of warcraft on the way creating competition between the same company.
Blizzard has not sent much news on the game but there are a few demo videos to watch on youtube or directly off of the blizzard.com site or diablo.com. The only other news has been the 2 classes: witch doctor and the barbarian, which both have a gameplay video to watch.
Blizzard is being very hush and not releasing much news on the game like they tend to do with all of their games. Pricing is still not able to estimate said one blizzard employee and there is much speculation whether there will be a monthly fee. The same employee said there would be a release for the mac and the PC simultaneously.
