I was wondering what could be causing all this secrecy and have made a couple of assumptions:
1. The older Mark gets the less he can be bothered - meaning he just wants to do his little thing and reveal it when it's ready, which leads us to...
2. It's probably fully recorded, mixed and mastered, has a title and a track listing. He's just waiting for the artwork and all the promo material to be ready.
We wouldn't be getting little nuggets here and there, just the whole thing all at once. I mean all the info, not the album itself.
