Early days, I know. However this seems, to me, to be the most plausible route the series may take considering a few different factors;
1 - Each main Kingdom Hearts title has had a Final Mix within a year of the original release.
2 - A HD release of Dream Drop Distance was decided against at this time because it is both a recent game (2012) and development would draw resources away from Kingdom Hearts III.
3 - Dream Drop Distance is on the table as a downloadable release or "something like that" in the future.
4 - Re:Chain of Memories was bundled with Kingdom Hearts II Final Mix in Japan, so this is something they've done before.
5 - Nomura intends to release a Kingdom Hearts game yearly if possible (at least until the "Seeker of Darkness Saga" ends).
So a Final Mix+ for Kingdom Hearts III incorporating Reream Drop Distance (or just a port, or a cutscene version at least) sounds like a realistic scenario to me. If Kingdom Hearts III is released in late 2015 or early 2016, then I would expect this to appear in late 2016. By that point 3D will be four years old and the development team can focus entirely on that without impacting Kingdom Hearts III's development. And I hope, if this is the route they do down, that the Final Mix is released internationally without a ten year wait this time.
