I personally feel that most all of this was going to happen with or without the Nasir album being released. This was all pre-planned ahead of time.
Nas formulated Mass Appeal Records back in 2014. They even announced that Lost Tapes 2 would be released via Mass Appeal and that Killer Mike (whose group RTJ would eventually release their second album on the label) would be involved in a compilation album.
Nas is going indie.

Nas still had one more album to turn into Def Jam and I believe instead of giving them the “Nas Album Done” record, he hooked up with Kanye and did the “Wyoming Sessions” to fulfill his contract and give him some added buzz and for Mass Appeal.
The only issue with that is Kanye was in the midst of becoming a full on c00n MAGA Psychopath and sabotaged the album by not having the beats ready until A WEEK before the album was supposed to come out. Which is why it sounds so rushed and didn’t live up to expectations.
Once he was free of Def Jam, Nas did what he said. He released Lost Tapes 2. He also fulfilled a wish to work with Hit Boy, whom he’d already collaborated with twice before on the song Another Black Girl Lost and the unreleased No Such Thing As White Jesus (which became Royalty on Lost Tapes 2)
Nas was working with Hit Boy on a Valentine’s Day themed EP that ended up becoming King’s Disease, so a project with Hit was always planned and in the cards. That it went so well and became a four album series maybe wasn’t planned. But i’m certain that Nas had tapped Hit Boy for his first official Mass Appeal project before Nasir was released.
