GameFreak, like most Western publishers, wants to establish a shorter dev cycle with faster releases.
For XY, they invested a lot of money into streamlining the dev process: a scalable engine, easy creation tools, new staff, and most notably the high-poly, reusable models and animations.
Other evidence of this: fewer Pokemon per generation and more reused Pokemon (to stretch out ideas over as many generations as possible and to have all Pokemon appear in the anime in shorter time), removal of the National Pokedex in favor of Pokemon Bank being your "link" between games, poor performance in the 3DS games due to the engine being "future proof", and obviously the short time between XY, SM and now the Switch games.
This is the reality of the situation and mirrors what tons of other franchises are doing: biannual mainline releases with "off year" games by B-teams using the assets from the last mainline release, and we might even see those mostly replaced by remakes and DLC for the main games.
