Better sales for a better fighting game.
Also Smash is a fighting of a generation (again), don't think any fighter this gen will come close to WiiU+3ds combined.

Highly subjective there. I personally like Street Fighter V much better than Pokken Tournament. Also I agree about Smash. I'm not sure any fighting game will sale as much as Smash this gen.
