There was a rumour that there was a possiblity of some Japan exclusives to come to Europe but that has since fallen quiet again. I mean, I'd buy KH2:FM+ just to say I had it (I did that with FFX-2 International + Last Mission)
As for the release of KH2:FM+ it hasn't been confirmd nor has it been denied and Nomura did he say that he wanted the English speaking community to have the chance to experience the Japanese version so take from that what you will.
I've not watched the Secret Video yet but have the HQ version here to watch at work tomorrow
