Looks like there's at least two "Cactus Jack" AJ1s in the works.
Travis Scott and Jordan Brand will continue their partnership in 2019 with several new sneaker collabs, including a unique, white and brown Air Jordan 1 with a backward Nike swoosh. Those are rumored to drop in April, and it appears they won't be the only "Cactus Jack" AJ1 arriving next year.
As seen in one of La Flame's most recent IG posts, the special edition AJ1 also comes in a tan and black colorway, equipped with the familiar flipped Nike swoosh in white on the lateral side.
According to sneaker source @PY_Rates, there's also a Travis Scott x Air Jordan 6 set to drop in 2019 featuring an "Olive, Black, Sail & University Red" colorway, similar to one of the exclusive "Cactus Jack" Air Jordan 4 collabs.
It remains to be seen if the olive and purple Travis Scott x Air Jordan 4s will ever release, but 2019 is already shaping up to be a big year for "Cactus Jack" Air Jordans, with or without the AJ4s.
