I'm a little confused, but I think that Welcome Home is like an internet single. They have the video for it up on mtv2.com. The next single is The Suffering, I just got it last night and it's poppy as fuck. It's like Favor House, Blood Red Summer, and 3 Evils combined (It even has the "hey hey hey's" from BRS and the hook is sung exactly the same as "Pull the trigger and the nightmare stops" was on 3 Evils)
They're also showing animated shorts on mtv2 for the next month that show the story aspect of the new album (Which is about the things the writer of the story is going through in his life and how it ends up affecting the story)
There's also a graphic novel being released the same day as the album that shows the story of the new album...
And also, Second Stage Turbine Blade is being re-released the same day as the new album. Remastered and with 3 bonus tracks. Elf Tower NM, Junesong Provision Demo, and Everything Evil Demo.
