Everything in Blue is either from Diamond, Pearl or Platinum's dex and everything in green was available with GBA insertion (which may not be back but maybe the Pokemon will be available somewhere else)
I would also venture to guess that they could retrofit the Pal Park into a sort of Pokemon preserve where random Pokemon that wouldn't normally be available can appear based on various conditions (either WiFi updates, random encounters or manipulating something in game)
