Did you read the interview? AZ said that the version of Doe Or Die 2 we’re about to hear on the 10th has been only really in the works since last year. With the Pandemic locking shyt down he really had time to bunker down and knock the album out. In his OWN words, he reached out to Nas after Kings Disease 2 released, which would be right when Nas started touring and doing shows. He’s got a bunch of shows coming up, plus interviews, video shoots, etc. all in support of HIS album.
Nas himself has said he’s been busy and hasn’t been able to get back to people. In the interview with Ebro he acknowledged people have been reaching out to him and he named that Jim Jones was waiting on him. Sometimes schedules don’t align. I don’t know why AZ would wait until AFTER Nas dropped his follow up to reach out for a verse. But thats how the cookie crumbled
