Just pointing this out. And no I don't hate the starters we will get. They are actually pretty cool. Anyways that whole split line thing came from a leak a while back that also mentioned Alola Forms and seems to be in connection with the Chinese leaks. Also the way Pokemon is going right now... Split evolutions will most likely be the secret the starters and Rockruff share since we can already eliminate Mega Evolutions, Z-Moves, and Synchro. Also the new bird Pokemon is more proof that it could happen
