I think it's great that we're getting a ton of fighting games this year.  The irony is that it was the Street Fighter series that, once again, made fighting games popular.  I don't think SF4 has made an impact as big as SF2 did back in the 90's, and that's because of the relative lack of an arcade scene (at least in North America).  However, I hope this resurgence means the return of certain franchises, like Rival Schools.
