>>49601847Now that they ACTUALLY updated models AND animations in PLA, it's no longer feasible anymore in a genuine way.
Right now there are 1,370-ish Pokémon forms in total. Let's say they were going to add the remaining 900~ forms that weren't in PLA to the game, they'd need to do the following for every single mon:
>update models (considering they have modeled mouths, eyes, etc. instead of just stamps)>update every texture map for color, normals, reflections, etc. (they've been using the same models between XY and BDSP, but the textures have almost always been different in regards of every game's art direction)>add new animations (from the top of my head) for moving around (which they do in battle), turning, dizziness, standing up; afaik the animations for attacking, joy, sleep have stayed the same>update size and weight tables, as well as other mechanics I'm not aware of atmIs GameFreak excused to not do this? Don't think so, but GameFreak is already terrible at delivering in other areas such as graphics, so adding mons isn't a priority.
Just think of how many Pokédex tasks they added for every mon and how obligatory completing the Pokédex is in PLA: they want to make absolutely sure that you see all of the "content" they added. So I doubt they'll ever prioritize adding mons with features/mechanics that may or may not be deprecated in the following installment and that 90% of the playerbase won't see.
