I think it will be a holiday 2021 release and won't be announced until the autumn. Nintendo saw the leaks and said "hell no". Either that or they purposefully leaked false info in advance to clear out the leakers before they start to prep for launch.
Or...they've seen gamepass and MS ambitious console free gaming plans and will wait a year for a better Internet offer, a bigger blue ocean innovation and slightly better innards in a bigger upgrade.
Take your pick.
