Nintendo is fairly consistent with directs. For the last couple years they've had a direct in February detailing the first half of the year (with one or two announcements that might bleed into the second half). They have a focused direct or two in between, as well as an indie showcase in April or May. In June they have a direct that shows games for the last half of the year. Almost every direct they've had outside of 2020 has done this the order is a little jumbled in 2018 as well).
The only thing that is indicating a replacement is imminent is the age of the Switch. But the game line up currently is not a good indicator as it can change at any moment.
Now if they DONT have a June direct and they also don't show anything in August/September...then I'll agree with you. But, right now, it's par for the course
