Your also basing this entire post on assumptions. Not saying D3 is gonna suck, just that the chance is there.
Chance that anything will happend is always there
I didn't mean to be offensive in anyway, just looking at trends, of all the people I know playing Blizzard games, and also the way in which Blizzard develops and test their games, are highly qualitative. Sure theres less emphasis on the actual graphics, but graphics means so little for most people once its above a specific level, also it allows way more people to enjoy the same game. Blizzard has been known for "spectacular" game-interface/gameplay, and the production quality always follows suit. I agree theres always the chance that it won't succeed like perhaps Diablo 1 and 2. An example could be SC2, they had all of their previous SC1 fans, and when SC2 launched, it surprised the world, ended up sucking 95% of RTS community to itself. If hardcore gamers are to litterally live off playing a game, SC2 is the game to play, Top-sponsored teams and community is all there, not even CSS community comes close to it..
