I know you guys just want KH3 already, but I really wouldn't mid another prequel game to be made explaining what happened in between BbS and KH, as long as the main character is King Mickey. I never played BbS, but was Mickey a Keyblade master at that point, or did it show him becoming one? If not, it should show how he became one.

I doubt that would happen

You mean BBSV2

I want that to happen

I never really cared for BBSV2.  I wanted a side/bridge game centering around Kairi and her training, fighting with the aid of the other Princesses of Heart in an alternate universe (similar to the Sleeping worlds, but not able to be hijacked, probably fighting ghosts of old enemies for bosses) to give her more character development before KH3 comes out.  

It's not gonna happen though.  After the ReMIXs KH3 will be next 'cause fans got pissed off with the side games.
