Yea true, a monopoly is never amazing to have, hopefully Nintendo doesn't get lazy in japan or even WW if the next gen gets a disappointing start.
I don’t think Nintendo will get too complacent simply because they've had some insane lows sprinkled in between their successes. The Wii U probably still stings them. Sony is the one that worries me when it comes to complacency.
And its not like Nintendo is trying to be complacent. Its just that they want to be sure of their release schedule, which could possibly change depending on how the world manages COVID-19. Sure, the rest of year appears to be set for their schedule internally, but they are also still exploring ways to present new content outside of Directs (i.e., the surprise shadow drop of the Paper Mario: The Origami King teaser). As we all know, Directs take months of planning, collaboration, and confirmation of release dates/windows. And filming. When they are ready to present what they want to show in a Direct format, they will do it.
Sakurai filmed the ARMS Fighter presentation back in early May in his own home, which released in late June. Think about that. And that's only for DLC of a 1.5 year old game. COVID has affected how companies are planning and filming their respective presentations.
