The only way to get your hands on the Blu-ray version of the Street Fighter 4 anime will be putting up the money for the collector's edition of the game, at least that will be the case for a little while.Will you be able to buy the Blu-ray version of the Street Fighter 4 anime separately?
Seth: There are currently no plans to release the SFIV Blu-Ray movie as a stand-alone. As it seems, it's designed to be an added feature for the Collector's Edition exclusively.
It could eventually be released as a stand-alone piece, I suppose, but even if that plan started today, it would be 6 months to a year before you'd be able to get it (and as I mentioned, those plans don't currently exist at all, so it may never happen).
