If Poke'mon did take over Springfield's area, I would guess there is no way the current food court remains an eatery with the way Poke'mon moves merchandise. That entire facility would be destined to become one giant Poke'mon Center store with the amount of money that franchise prints. That'd leave them with the former Luigi's/Duff/Ice Cream and maybe Kwik-E-Mart spot for some kind of eatery or snacks.
