3s was way more complex than SFII and also came out at a time when fighters, esp 2-D, was passe to the average gamer.
SFIV will be a hit for Capcom because it's a repackaging of SFII in 3-D, which is what the average gamer wants even if it bugs a lot of people who actually play SF. Oh, and the online won't completely suck like every other fighter besides SF:HD and VF5 (which no one cares about sadly :P)
P.S. 3rd Strike was released with Hyper SFII for Playstation 2 in, what, 2004, and sold wayyyy better than Capcom thought it would.
