that gave m some h0pe... if he is a full time member i believe there will be some changes.. i doubt jon allows the guys to play wherever they want which may cause program conflicts for one..
even if that was the case though jon would still stick to phil just for safety, or perhaps shanks gives him that nowdays...

ps. Phil x is respected in the band and fans for sure but he doesnt fit in the band, and its obvious by hiw role, his part, everything. in fact it seems like jon never gave him a chance.. or maybe he early on realized he was there only for the guitar pyrotechnics and nth more
