Why would GameFreak etc. respond? I mean, Yokai Watch came out and was massively popular, Pokemon didn't need to respond to continue to thrive. Digimon made a come back (and IMO produced a game that was better than any Pokemon game has been or probably will ever be) and again they didn't need to do anything to respond.
Bet Shiken that COD would outsell Battlefield in 2018. http://gamrconnect.vgchartz.com/post.php?id=8749702
