Could Pokemon 2019 make use of DLC like other Nintendo titles have been?

As long as it's outfits and such I wouldn't mind. If they try locking gen 8 mythics behind a paywall or something I'll be pretty ticked, and I'm sure alot of others will as well. I would love to see an expansion where you can visit a 2nd region [nonsensical jargon]

I can't see them locking mythical behind a paywall. They have never done it and I can't see them starting now.
