Why did Pokemon even jump to 3D?

Gamefreak make Pokemon games the market wants, more of the same. The series has been selling an incredible 15-17 million copies per major entry for nearly 20 years. This is why they are the biggest entertainment franchise on the planet.

They won't make any drastic changes to Pokemon unless sales suffer, don't fix it ain't broke.

Having the national Pokédex available in every game wasn't broke, though. Pretty sure this is a case of them, quite clearly, breaking it.

Ruby/Sapphire didn't have a national dex as you could not transfer older Pokemon into the game until FireRed/LeafGreen came out. I expect the same thing for Sword/Shield to happen next year when the Diamond/Pearl remakes are released. 

Either way sales for Sword/Shield will prove if the majority care or not, or it was just a vocal minority.
