Rumors
In a 2Pac forum, there featured a post which had a supposed confirmed Afeni Shakur interview from Time magazine. One of the questions asked was: "Are we to expect any new Tupac albums?" Afeni's reply: "There will be a new album released at the end of the year and the album will feature some prominent hip hop artists, plus new material."
Rumors surfacing the internet include tracks being produced by such artists as Dr Dre, The Neptunes, Kanye West and 50 Cent.
Various hip hop sites, posted reports that 50 Cent wanted to produce 'the next Tupac album,' (which is now confirmed as the November album being released). How ever, no news has been posted since regarding 50 cent producing the album, it seems the new Tupac album with have various producers, one of which could still be 50.
Other interviews on Tupac forums, have suggested supposed confirmed guest appearances will be: Ne-Yo, E-40, DK, Papoose, Young Dre, and a track with the Notorious B.I.G and other dead rappers.
These are just rumors, nothing has officially been confirmed from reliable sources, though confirmation on the new Tupac album is set to drop very shortly.
