Nintendo really doesn't do much backing of Smash Bros. Ultimate when it comes to the eSports scene, which has been a real point of contention for fans. That said, it seems Nintendo might be looking to restart their efforts on the college side of things.
PlayVS is the "Official Platform and League for High School, Youth and College eSports." The organization was looking to offer some Smash Bros. Ultimate tournaments in Spring 2021, but apparently Nintendo stepped in to call things off. According to PlayVS, this is because Nintendo "wants to wait to restart their college initiatives at a later date." Obviously this isn't super specific, but it is a glimmer of hope.
