So is this the Animal crossing Switch edition?
No, because it doesn't line up with the dates claimed in the rumor. All those units should be produced by now to be ready to be shipped worlwide and be in stores by mid-March (ships take weeks to reach their destination). But technically, the rumor could have indeed concerned a special edition all along.
There was always the possible outcome that the entire rumor is bogus and that might very well be the case here. Nintendo made a clear statement in their presentational material for investors (top of page 10):
"Please note that we have no plans to launch a new Nintendo Switch model during 2020."
In theory, those plans can change within this year, but it's not looking likely.
