Well we do know that he bought a home and is currently living in Miami because that is where he is recording. A Stapp fan site reported on the name of the recording engineer in March, and e-mails from the man indicated that some recording had already been done. The dude is working..he just isn't reporting his every move.
Its not alot of information....but people handle publicity in different ways. Just because he doesn't have information out there doesn't mean he isn't doing anything. I can remember before he publically announced the solo stuff, people were stating that they didn't think he would do anything solo, that nothing would ever materialize...that he was just all talk.....I guess they were proved wrong.
