>but muh SPECIAL typesIt's been almost 20 years since the last game without the physical/special split. Half of current GF staff probably have no clue about that pattern anymore and they've been all about breaking long held patterns lately.
>but the group merch! a new eeveelution would kill sales!No. They'd add the new ones to collections of individual pieces, discontinue full group items, and release new/updated designs with the new ones included. The kids and collectors will just be glad to have more to buy because this fanbase will buy anything and eevee fans are particularly big on buying merch.
>there's other ways like new forms/mon with the same gimmick, or 2nd evolutions with the other typesI've yet to see any fan version of this that isn't awkwardly shoehorned together. Eevee being a mascot now they wouldn't want to change it too much (see gigantamax just being fluffier) the same way they treat pikachu. The popularity of pikachu vs its clones almost nobody cares for compared to eevee which is only boosted by it's evolutions gives them hard data (merch sales) that shows they'd be stupid to try to duplicate it with another form or copy it with another pokemon because it'll never be as popular as just adding another evolution.
