From the few interviews I've seen and read with Steven, it really seems like he is leaving the door open for PT to continue. Heck, the album name is pretty much a big sign for the band to be on-going, but Steven has already announced his plans for another solo album. Will Richard and Gavin sit by while Steven goes off on another solo adventure, only to wait for another PT album, or will Steven put his solo work aside and see if PT should continue touring/writing/releasing music together?
The chart success for C/C might help Steven reconsider his plans, and if the tour is a huge success with shows at near capacity, he might be even further persuaded to continue PT for another album/tour after this year. It's a very "Wait And See" situation right now, but honestly, like many of you here, I'd say C/C is probably my favorite thing Steven's done since The Raven or HCE, and before those, it was FOABP.
As for the tour itself, I'm sure they'll play all seven songs from the main album, but I could also see the band not doing all of them and even tossing in one, two, or all three of the bonus tracks as well. Either way, it'll be a treat to see them play this material live! Hopefully the shows are packed so the band can see just how much their return means to the fans, but given how expensive tickets seem to be (the DC show has tickets over $200...yikes), I can see fans opting out of going, especially those who already feel cheated into having to buy the album twice (because of bonus tracks, or delays in receiving they physical product). I'm not much of a concert-goer, and prefer to buy physical products and some t-shirts to show off my fandom and appreciation of bands I love, but one of the few concerts I've gone to was Porcupine Tree on their FOABP tour (in Baltimore), and that was an experience! I envy everyone who can manage to go these shows and experience this band live.
