Would there be a possibility for another posthumous album?

With all these new leaks and everything, there's a lot of unreleased songs, I mean there's a whole ep name "People/ 1/8 2 da face" with only one song out of three that has surfaced which is Jon snow, then there's just in case, lonely/on the highway, don't panic, etc. What im trying to get at is that there's still a good amount of high quality songs, do you guys think it'll all be released as singles, possibility for another posthumous album, or just never officially released?
