At the FFXII launch in HMV, Oxford Street, my friend had a couple of questions based on KH, which he asked the Square Enix Marketing Manager. You may or may not want to believe it, but this is pretty much re-assuring the KH fans of future projects.
F = Friend SEM = Square Enix Marketing Manager
F: Hi. I have to ask this on behalf of all the KH fanboys in Europe. Can you PLEASE bring KHII: FM+ to Europe?
SEM: *Laughs* We have big plans for the KH series this year globally. It has become a big series for us.
F: But will KHII: FM+ hit Europe?
SEM: I think it's safe to say you will be pleasantly surprised around the end of the year. *grins*
F: What is the future of KH like?
SEM: Well KHIII is going to be released on PS3 and we will see what we can do with that.
F: What about a KH movie? Advent Children was sick!
SEM: Well you never know we are good at CGI aren't we? *grins*
F: Will we see another KH game on a Nintendo platform?
SEM: Well like I said, there will be big KH related announcements made this year. Please look forward to it.
F: Will KHIII be a new trilogy with new characters?
SEM: Can't answer.
That's all the questions he had asked, even though none of this is confirmed information, like I said before it's re-assuring. The rest of the questions were about FFXII, which we aren't interested in as the game is already released :).
Edit: The magazine Famitsu confirmed that there won't be a announcement concerning a new Kingdom Hearts game at the Square Enix Party.
Edit 2:
~Final Mix will be Nomura's last PS2 game.
~In the scene with Axel and Roxas eating icecream there is no voice acting, this is on purpose.
~"The battle with Axel can be reproduced. The enemies' data seemed to
have been strengthened. Everyone is individually looking unpleasant.
The nature of the fight isn't complete even if defeated." < This doesn't make much sense to me sorry. >.<
~To defeat the Org members there is a particular strategy to use instead of the button mashing. Using the correct methods will make the battle an easy one.
~KHCoM has a new cutscene at the end.
