I am sure that they are hoping for a fully blown tour given the right offer comes their way. It's all matter of time. They got nothing to do until 2008 anyway .
Haven't you noticed the pattern. Release an album in the fall, tour year and a half or so, write during the winter/spring, record early summer and repeat. I'm sure they've got certain contractual obligations to releasing album/s at certain frequency. Most seasoned bands follow similar one.
