Amiibo line of business has been important for Nintendo not in a vital way, but important to strength their products. The strategy could be different with Super Mario Maker 2.
Some online fans have noticed that the promotional poster for Maker 2 does not have Amiibo logo on it like other Nintendo products. This is just speculation, because Nintendo could announce a series of Amiibo articles for this game, but right now that’s the line. No Amiibo logo, no support.
Just as an exercise of comparison:

2. Super Smash Bros. promotional poster:
We will see.
