Hey guys I hope Diablo 3 works good on Dial up over battle.net 2.0

System requirements for World of Warcraft include: "You must have an active broadband Internet connection to play."

I think it's reasonable to assume that the same requirement could apply for multiplayer components of future titles. Which isn't to say a dial-up connection wouldn't work, but if you fall below the minimum system requirements your play experience wouldn't be wholly supported.

Bottom line though is that no system requirements have been announced for Diablo III, so I wouldn't put too much thought into it just yet.
