JT confirmed today on OtherTone radio (Beats1) That him and The Neptunes were back working together on his new album, it's still in its infancy so it could sound completely different by the time its done but what the ideas they've been working on are crazy (Tyler the creator was a guest on the show and said he got to hear a song and it was nuts). Said it might be awhile before they're done, wont be a quick turnaround like 20/20 vision (recorded in several months)
