The PS2 era is (arguably) over, but not forgotten. Kingdom Hearts and Kingdom Hearts 2 were two of my favorite games for the PS2, and i was always into the idea of playing Kingdom Hearts 3 on a "next generation" console.
Needless to say, it hasn't happened yet, and i don't know that it ever will. It has been years since Kingdom Hearts 2 was release on the playstation 2, and all we have seen from the series since was a few unappealing portable games...and my interest is fading.
So, how long can a series be away from it's core audience before people lose interest? Is it too late for square to try and release a Kingdom Hearts 3?
