At this point Jay Z (And Biggie from the grave) is the last Platinum Rapper in New York. Nicki's last album tapped out at 800k. NaS is pushing 400k so he's still basically a Gold artist at this point. LL can't sell anymore his last album was the lowest selling of his career. Wu Tang as a group and solo's ain't moving units like that anymore. Method Man is the top seller of Wu Tang and I'm sure he can't go Gold anymore. ASAP did pretty good but he didn't go Gold. Talib and Mos never been huge sellers, doubt they are going Gold now.
Lil Kim waiting way to long after Prision to release an LP, Don't know if she could go Gold. Foxy definitely isn't selling. Diddy Last Train to Paris didn't go Gold. Ma$e can't sell anymore. 50 Cent has pushed his album back for 5 years and "Before I Self Destruct" barely went Gold so I don't think he's going Platinum or Gold anymore. Busta could do good but I don't know about Gold. DMX last album flopped badly. Ja Rule just got out of Prision and hasn't sold well in years. The Lox, Styles and Sheek are basically underground now and won't move units. Jada could possible go Gold with the right singles but I don't know. Fabalous probably won't go Gold anymore which is why he's doing more mixtapes now. Mobb Deep I don't think can go Gold cause P and Hav solo's both sold lukewarm. Everyone else is either Retired, Touring or not Releasing albums. Jay Z is literally the last of the New York Hip Hop Dynasty.
