Fuck me, those screens look nice...too nice. "Need to buy a new computer to run it" nice. :P
That's what I'm scared of too. Seems like Blizzard has always been kind on the hardware requirements front - I hope they will be this time as well.
Didn't really strike me as gameplay that looks like it'd be too hard on the hardware requirements, but then by the time the game's released, you could probably make a computer that'd meet the suggested requirements for a couple hundred bucks tops.
Anyway, I threw in enough hours in Diablo II that I'm tentatively excited about the game. It's easily my favorite Blizzard franchise, at any rate.
