Do you think Diablo 3 would require a very high end system?

Too bad, the system requirements aren't in the Diablo 3 site yet. It may very well be a top-mid or high level system that could play Diablo 3 with stunning graphics and excellent playability. It's really hard to keep up with PC technology especially if you're earning just enough. Hopefully, Diablo 3 won't require too much PC power. I haven't upgraded my PC in 3 years. It can still play new games buy I have to sacrifice the quality of the game. It disappoints me to play with blurry 3D images. I'll be upgrading real soon. take care!

Blizzard will do the same thing with Diablo 3 that they did with Starcraft 2. SC2 has a wide variety of settings, it can go super high or very low. I can play it on my two year old laptop, running XP, and a friend of mine can play it on his laptop that is only 6 months old, running Windows 7. Blizzard knows they need to make the settings good enough to please the hard-core gamers with cutting edge rigs, but still accessible enough to get a huge market share. Diablo 2 is still incredibly popular, so much so Blizzard is still developing patches for it. They are not going to shoot themselves in the foot with Diablo 3 by making the minimum requirements super high; they have been in the industry long enough to know not to do that.

Blizzard usually makes it a habit to put out games that will run on a wide variety of systems so even if the graphics in a trailer look great there's usually enough options in the game that you can tune down to make it run ok on a sub-par system.

yeah i dont think they will require a "For a requirement for mid-to-high-end pc only". Blizzard usually makes their games run in a wide range of pc specs. that's one of the best thing to them
