Rob did say that yes, but Chester is going on tour with STP at the time which raises the question: Are Mike and Brad going to write the entire record again and just have the rest of the guys come in and play their parts or are they taking that much needed, in my opinion, break?
About the sound, we can’t really know, they don’t even know. They may say this now but they always tend to change their initial comments.
Lastly, as for THP songs not being played live, I’d love to see them play a few more but considering their set and the difficulty the newer songs have, I don’t really blame them. Better not play them at all than try and mess them up big time.
