I know what game it is. But it’s so outlandish if I told you what it was you wouldn’t believe me anyways. But when it’s announced I’ll be laughing. ;) https://t.co/zwvxtsFy7M

One hint: it’s not a Nintendo game. That is all. I have spoken!

This is exactly what I pointed out earlier in that he said cancelled game not cancelled first/second party game so it's another Bayonetta/Devil's Third situation where the game likely had nothing to do with Nintendo or their platforms.
