I don't think Jon will open up the vaults until he decides to officially retire the band for good,which I doubt he'll do anytime soon. Jon also said there will be box set coming out in a few years but I doubt it'll happen,besides if Jon really does decide to release a box set then he'll probably have all of Richie's backing vocals and guitar parts removed from the songs just so he doesn't have to share royalities with Richie,exactly what happned with Burning Bridges.
