I used to care about album sales, but I really could care less nowadays. They just don't seem to matter...High Rise may sell around 15k in its first week, but it'll probably still be in the top 10. It's not like it's going to be at number 50 or number 100 or something...this isn't "Happy" In Galoshes here. If the music's good (which I think it is) and CheSTP can tour and make new music, that's all that matters.
EDIT: Also, Out of Time has already been a solid hit, and I can see Tomorrow and Same On The Inside being even bigger
