How many versions of Versus are there?
 

I saw a review for what looks to be a really cool Japanese shoot em up/action movie called Versus yesterday, and immediately I was intrigued. I looked on amazon to see the release date, and there were supposedly two versions, one that is already in stores, and one that comes out August19. Was it just a typo, or is there already a version out? What are the differences?

I just realized that I posted this in the wrong forum...ill move it to DVD talk
