Bringing the Thunder
I didn't even think of that. We could have a lot more possibilities now that we're capable of getting DLC since it's on the 3DS. I could see them making an area the size of the Sevii Islands, Sinnoh's Battle Zone, or possibly bigger, as DLC. They could even add areas where we can get legendaries from previous generations, instead of just having standard events.
That's what I was thinking too. You'd have access to completely new areas with Pokemon not seen anywhere else in the game, legendaries also not seen elsewhere, possibly some new features (maybe a Battle Frontier/PWT or Contest/Pokeathlon/Musical/PokeStar Studios type place), and even a mini storyline.
