lol it's because these aren't the best pop-punk bands, so referencing to it as the "ultimate" pop-punk tour would probably turn some pop-punk fans off.
Even if they aren't the best, they are all solid choices. I'd rather have 3/4 solid choices in a tour than have 1 great and a bunch of crappy scene bands that their label forced them to tour with. That seems to be a trend nowadays. I happen to adore FCC, and although they aren't the most original, Real Friends are great live. I'm psyched for this tour.
