Which franchise will win in Japan, Pokemon or Youkai Watch?

[Darwinianevolution]

The surprising popularity of Youkai Watch has probably been a  surprise for everyone this gen. The game keeps selling really well in Japan, and it doesn't seem to be slowing down, at the contrary. It's even threatening the dominance of Pokemon as the monster-collector champion, a position it has hold since 1996.

Pokemon this gen (main series, not spin-offs)

Game	Platform	Year	Genre	Publisher	Japan
Pokémon X/Y	3DS	2013	Role-Playing	Nintendo	4.29
Pokemon Omega Ruby/Pokemon Alpha Sapphire	3DS	2014	Role-Playing	Nintendo	2.69

Youkai Watch this gen

Youkai Watch 2 Ganso/Honke	3DS	2014	Role-Playing	Level 5	3.10

Youkai Watch	3DS	2013	Role-Playing	Level 5	1.32

Even if we assume there will be a Pokemon Z or a Youkai Watch 3, which franchise will become the king of the monsters this gen?

P.S. When is YW coming to the west? Is this year or the next?
