Let's get this out of the way. Since so many people still deny the first pair of Switch games will be gen 8, they will. This has nothing to do with patterns, nor what I want, but everything to do with maximizing profits.

Gamefreak and TPC have made it clear that they are nervous about the Switch's install base compared to handhelds, ontop of the greater development cost. They will need more than ever to maximize sales. What has been the biggest seller for Gamefreak? New gens of course.

The time for experimentation on launch games is not now. Gen 5 and 7, which were on the same handheld as the previous gen would've been the perfect time to do such things. However if Gamefreak wasn't willing to change things up then, why would they now when the stakes and expectations are higher?
