I bet they are Todd. 
I'm fine with wait &amp; see, but admit I'm rooting for John Rogone.
Saw him play with GPN 3 nights in a row (Ellsworth, ME &amp; the 2 Fredericton, NB shows) when he was filling in for Cat.  Thought they sounded great, the stage 'look' definitely worked, and of course the musical connection was already there. 
But then I believe in promoting from within whenever possible .. for one thing you don't have to keep explaining the jokes. :)
