Maybe 20 years from now when people who are mad at Amaru get over being treated like shit and hand over their DATs, but this definitly wont happen for sometime.
The Hendrix thing is also alot different because his material didnt get bootlegged anywhere near the extent that Tupac's has.
Why would Amaru pay to press up a CD that has essentially been download for years online? Because it would have better quality? In that case look to the remaster album sales and you'll see that it's not really a profitable process. Im actually suprised they are remastering the albums, I guess its just a means to milk out the last dollars from those CDs.
