Given Capcom's current track record, smart money is on never. So plan on that and at worst you can be pleasantly surprised.
I would expect some type of spinoff or port on Switch. I would expect Monster Hunter World 2 (or something similar) to be announced for next generation though (probably cross gen as well).
Don't hold your breath. Capcom has released 0 - count em, 0 - new games from Capcom outside Mega Man 11. Generations Ultimate is the closest thing to new we've gotten otherwise. The rest are old ports or midlevel remasters, most overpriced. After the RE4 and Collection pricing disaster and that RE5 and 6 trailer from E3 that was just oozing with smug self-satisfaction as if bringing the two most maligned REs to Switch is deserving of high praise, I expect nothing. Absolutely nothing outside maybe Mega Man games.
