D3's gameplay looks top notch, but the graphical presentation dissapoints me a lot. It's just not hardcore enough for my taste in comparison to its predecessors. If I wanted World of Warcraft I'd play World of Warcraft.
And that gameplay video they showed on WWI rocked, i can't count how many times it amazed me ( the physics, the combat, the monsters, the Witch doctor, the ZOMBIE WALL and finally the Siege beast that chopped the poor Barbarian's head ... i was like .. what the, did that just happen !!!! )
I'm now obsessed with both D3 and SC2, hope i can manage the wait
