In terms of developing relations, I think Nintendo has gone the furthest with the Smash community. A couple of days ago Genesis 4 announced their collaboration with Nintendo.

What does this mean? Well, it means that there are a lot of logistics, hardware, managment and support that Nintendo does behind the scenes. Outwardly However, if there is any indication with when the promoted Splatoon, I have a feeling that they are going to promote other games as well. I think ARMS is going to be their top choice.
EDIT: Confirmed
Trying to convince @JCDotface to put me in Arms with my Arms but he's not buying it. And yes Arms is at #G4 on Switch this weekend! pic.twitter.com/2qZLi1gvse
