Maynard was just in Boston on the wine tour. Completely forgot about it. He was interviewed on WBCN. I haven't had a chance to listen to it yet, so not sure if there was any Tool info. Here is the link:

EDIT:
Listened to the interview. Here is a run down of the Tool related stuff:
Maynard doesn't know why they're touring.
Maynard has no idea if there will be another show closer to Boston.
Maynard said Tool are 4 completely different personalities that barely get along.
I got the impression that Maynard hasn't been in the loop much outside of being "tricked" into touring. Of course, most of it could be tongue and cheek.
They will be at Whole Foods in Cambridge tonight and tomorrow.
