I got thinking, and I think I figured out what's happening for the Collectors Editions of this game. If they release 3 different collectors editions again, then the Beyblade's that come with each different on will probably be: Bakushin Susanow Luna Eclipse Version, Nightmare Rex, and either Divine Chimera or Vulcan Horseus.
I'm guessing that Bakushin Susanow Luna Eclipse Version will probably be available at pretty much any store that sells games, since it was listed on GameStop.com
If they release Nightmare Rex (Which they probably will, since that picture was posted by To.) It will probably be exclusive to a store. Much like Cyber Pegasis was, last year.
If they release Divine Chimera (Which I hope they do, and they probably will, if they want to release 3 versions again.) it's probably going to be exclusive to a store, too.
Personally, I hope that they release Divine Chimera, and that Vulcan Horseus
doesn't get released with a game. I would rather Vulcan Horseus be released as an individual Beyblade so that I would be able to get Divine Chimera with the game.
Then again, this is all just speculation here...
