Maybe he's talking about his two projects with Neal Morse? That would seem to keep him busy, and rumor has it that Mike is recording this week in Nashville with Neal for his Testimony 2 album, so flying from Las Vegas to Nashville and then recording a whole album...that's quite a lot to do. Then there's that Morse/Morse/LaRue thing he's doing, so if that isn't already done, then he'll have that to do in the coming months.
I hope it's not anything related to his past vices, or even worse, family trouble... perhaps he is just concerned about the hype surrounding the new DT drummer? I would be to, to be honest...
