The Sunset Horizons concept video was just that, a concept video. Meaning anything and everything within that video was subject to change. As of now, we know that the focus is still on the three knights, but that's it. Nothing else in that video is canon, MX doesn't even appear in it. You should basically see it has a trashed concept with the FM+ secret ending being something close to the final product(which is BBS).
^ this.
Simply put, since that was a concept video, you can't assume everything that appeared there is relevant to the current game in development. In all likelihood, most of those ideas may have been scrapped, including the concept of a keyblade war. This can be implied from the BBS secret ending, which has no reference to a keyblade war of any kind. Or even the current BBS trailers, which makes the main focus appear to be the quest for the hearts of pure light.
