See, I never thought why people think that the secret ending means a DLC episode. I'm not opposed to it, if it means more KH goodness sooner rather than later, I'm all for it. But, why? Is it because of the Foretellers and the whole Verum Rex thing "seemingly" not fitting into the picture? Cause if so, I'm not quite sure if that's where we're heading.
Nomura also said he would rather do a new title rather than something like this, if memory serves, so I think this is KH4 stuff. But it's hard to say, it's the beginning of the year, and I like to think that KH3 will have similar update consistency like FFXV did, minus the Episodic stuff (unless Nomura or Square change their minds). I don't think KH3 will be updated two years later like XV did, but I do think we'll be seeing a lot more this year, including whatever the hell is going on with Verum Rex.
