The games now have the 3d models made that they will reuse until the end of time. Think of how easy oras must have been to make. The models were all from X, the base game from some GBA games. Pokemonamie/super training/etc. are all from X. Move tutors from B2/W2.
All they did was model the map, make some new megas, and remix music. That doesn't take a fucking budget, they just wanted it out in a year.
