Amaru Records could put out albums past 2010 if they wanted to. Despite claims of the 2006 album being the "last" Pac album, they'll have well over five albums' worth of unreleased tracks left that we know about. In addition, they'll probably put out previously released tracks in their original form (Late Night, Who Do U Believe In), remixed form (Fuck Friendz, Niggaz Nature, When I Get Free, My Block, Loyal to the Game), or put two versions of the same song on the same album (Let Em Have It, Thug N U Thug N Me, Until the End of Time, Fair Xchange, Thugz Mansion, Hennessey, Crooked Nigga Too, and Loyal to the Game again). So this type of approach adds another 10+ songs over another few albums. Also, consider what Afeni said in the Until the End of Time booklet... she intended to remix and release every last Pac song. And even if the next Pac album is really the last, they could go around their words and release the One Nation project (technically not a Pac album) or put out Pac songs on soundtracks or whatever.
