Well no-one can say for sure. My opinion is that it won't, games that uninspired rarely do.
SF3 had a slow burn to glory, it wasn't given much of a chance when released. It never got a timeley major home console release (sorry Dreamcast, but you were niche), and was overshadowed by MVC2, A3, CVS2 etc and an overcrowded (and then dying) 2D fighter market in general. But it came back from all to become the legend.
SF4 launched with a bang, hits a much emptier market, is clearly positioned to cash in on nostalgia for SF2 by including all the characters identically dressed, and has timeley and major home console releases.
I think it will be a flash in the pan in the end, the game just doesn't have the inspiration to become a keeper. It's a flashy, fun, but empty re-tread.
