Not to dissapoint gamers who eagerly waiting for the game but judging from Blizzard past experience they will polish the game until its perfect. Therefore do not be surprised if it came out at 2010.

Blizzard like to entertain the masses not only the enthusiast (CRysis), therefore i seriously doubt you need a killing rig to play this game effectively.
Rember that RPG games has the most high record of bugs compared to other genre. Look at games like oblivion, witcher, neverwinter nights series
you will get the picture. The reason why Diablo has so many fans it is the (gameplay) not graphics. Wait patiently lo.
