I'd like to think, eventually they'll stop adding new regions and Pokemon, settle down on a certain battle scheme, tweak all stats and movesets and just have it updated every year or so. Or at least that is what I hope.
Hopefully they don't keep coming out with new Pokemon, new evolutions and new regions because one, you're going to make Pokemon a little gay like Digimon got, two, there are already some Pokemon they shouldn't have messed around with by giving them evolutions and three, how big of a world can you make before you realize hey, I think ten different continents are enough XD
Agreed. Although, since the regions are based on Japan, maybe they'll be done creating new regions once they run out of Japanese areas to base the regions off of?
