Anyway, the staff members were basically saying that they will introduce less new Pokemon in upcoming games because they believe the number of Pokemon had grown too much.
I think that's for the best. We've got plenty of filler Pokemon now, I think its time to shift Pokemon creation to ones which, for a lack of a better way of saying this, "competitive". Make Pokemon that I want to use, have interesting gimmicks or fill a niche, maybe ones that revamp/re-invent old Moves, Abilities, or stategies. Shake-up the meta in ways we wouldn't think it could be shook up.
Also introduce more pre-evoutions, evolutions, forms, Mega Evolutions, and regional variants to give older Pokemon a time in the limelight. We've always want new Pokemon, but what some players don't realize is that we also want to see the older Pokemon getting added to and improved.
