I think if Nintendo continues to support by releasing more packs + ways they can interact together, then it'll give it solid boosts.
In my opinion I think it needs to get Viral. And that could be from any source in the world. We are seeing with Ariana Grande that singers can perform their song with using Labo.
Or it could be just allowing the Switch userbase to increase more from games like Pokemon, Smash, Animal Crossing and Monster Hunter.
