Rumors have been floating around for a bit now about what RIM will call their future QNX based OS when it migrates off the PlayBook and onto phones. It obviously cannot be called the BlackBerry Tablet OS anymore and CrackBerry posited that it would be called BBX merging BB with QNX. Now Kevin scored a slide from the QNX Auto Summit Japan presentation that seems to be pointing to the BBX name again.
My Japanese is nonexistent but you can clearly see it shows support for BBX, iOS, and Android. Let us know if you can figure out what it says!
