Can't wait to see the track lengths. I have a feeling we might get an "epic", like Octavarium or ACOS.
I predict something a bit shorter than ACOS/8V, but longer than the "epics" of ADTOE, and still noticeably longer than anything else on the album to warrant the title of the epic. I'll guess around 16 minutes. I'd love to see more songs like TTT, where they cram a lot of sections and changes into a shorter space, and progress linearly.
While it's a somewhat trivial detail, it would be nice to get track lengths, although I don't believe those are typically announced. I also don't expect a single, although I'd like to be wrong. I'm going to guess they'll announce the date of the single though, and I don't expect it will be far off either way.
