I highly doubt that. Though Nuclear Blast has many many bands with them, In Flames has to be one of the more popular ones on their label. As for the US tour; IF needs to support their new album wholeheartedly, and skipping out on the US would do a lot of damage to that. With their evident growing in popularity, they're losing some of their old fan base, and with touring in the US, they have better chances of picking up new fans along the way. Heh, besides, I will be very upset if their is no US tour, so there better be one!
