Now; what do you think Niantic will actually do:
With Mime Jr, a new challenge for Niantic arises.
As far as I can see they have 4 options.
Option 1. Make Mime Jr a regional egg.
This would mean that only eggs from Europe would hatch Mime Jr.
Option 2. Mime Jr goes worldwide, but unevolveable.
This would mean that Mime Jr would come out of eggs worldwide, but would not be able to evolve outside of europe.
Option 3. Mr Mime is swapped. Mr Mime gets changed for a different European regional. Mr Mime goes worldwide and a different regional exclusive is chosen.
Option 4. Regionals are removed. Regional Pokemon are all made worldwide. Every area with a regional pokemon now has all the regional pokemon.
I’m still missing Kangaskhan, I was lucky enough to go on trips to Asia and Europe for other reasons, but I don’t see any reason to go to Australia just for a game.
