I do not believe it to be Gutt or Borja and while I'm certain they gave it every effort to listen to those that made submissions, the open audition was nothing more than publicity for the band. That is not to say if someone blew them away they wouldn't entertain hiring that person but they had some guys in mind before all this and timing had to work out.
I don't believe the guy they have is anyone that has been rehashed over and over here but I haven't been around here much. When I do check in, it's been the same couple names that I've been told weren't their choice.
after reading the last couple very recent interviews, I'm pretty confident the name I've heard, could be the guy they are playing with. If it is, they are in good hands and I'm confident fans will be happy with their choice.
