Stores in Japan have apparently run completey dry in terms of Street Fighter IV as reported on the Capcom-Unity blog:

There ARE no more copies to sell on the store shelves. I heard from Ono-san himself last night that Capcom has a few boxes left in the basement that they’ll be sending out on Monday, but they were totally overwhelmed by the demand.

So there you have it; If you had any doubts that there was only a small market left for Street Fighter IV, your doubts can now be put to rest. But will it sell as well in the USA as it did in Japan?

I guess we’ll have to wait until the game’s February 17th Xbox 360 and PS3 release date to find out.
