I think this is the only sane way to interpret the data. It's astounding it's taken this long for KH to come back to consoles. Even moreso when you consider it's because of the struggles of completing FF XIV & XV.
Limbo sold about 400k WW its first month on XBLA, and it has maybe 1/10th of the content. Journey set records fairly recently PSN. The crowd is there, just not at $60. Origins eventually crawled to a million once it was discounted, this will probably do the same.
