Word from Capcom’s blog is they have completely sold all launch inventory of Street Fighter IV. It seems they were completely taken off guard by such a high demand.
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. Sales couldn’t have been any higher because every single day-one copy in the stores was been sold (!!!)
