I'd like to think, he'll keep going for a few more years yet. I'm encouraged by just how much touring he's done this year , to me that indicated that he's still very interested and hopefully the (relative) commercial and critical sucess of ROTT will inspire him to carry on. Ok, I know ROTT may not have sold millions (I Believe) but compared to say, the "Soutpaw" or "Maladjusted" era, the singles would appear to be selling a little better, lets hope this trend continues with "ITHFWAIW". & of course, the tour sold very well...so heres hoping.
