Sadly I doubt they care, this is about one last big pay day, so they want a line up that sells more tickets.
I think the new tracks added to the tracklist is the only fan service we'll get, but maybe I'm wrong and they may have guests for certain tracks etc. and I'd imagine the likes of Redman, Nas, Mary J may possibly appear at some shows.
I'd also expect that RZA will give the Killa Beez the Jay Z/Kanye treatment and make them buy tickets for the shows lol
