re: Art/Hoagland -- they've always had, on-air at least, a rapport that challenges each other. Not quite adversarial and not vituperative, but Art *constantly* called bullshit on Hoagland's... well, bullshit. Remember the one show where RCH had this absolute rock solid photographic proof that there was an intelligently-made structure on either the moon or Mars? IIRC, Art said something like come on, it looks like a cat box. Bell would frequently get under RCH's skin. Bell always added a healthy dose of skepticism to RCH's moonbattery. That said, even the worst of enemies can patch things up.
re: would/would not return -- this is such a wild card. Art could truly say fuck it, it went to pot, I have a wife and kid, screw the workload. Art also seems to have a healthy but competitive ego and want to 'get back in the game.' Barring Art (god forbid like Roger Ebert) losing his ability to talk, he could technically do a top-notch show well into his 80s. The issue, i think, is the production. Art had Ramona on production duties, and she had radio experience. They did a fantastic job and were a great team behind the scenes.
If Art could assemble a team he trusted to produce and basically just show up with minimal show prep, he could ostensibly limit his workday to 4hrs + 1hr pre-show prep.
Also, Asia is nearing an age where she'll be attending school full-time soon. He may just get a bit of a 'come out of retirement itch.'
Or, it wouldn't be out of character for Art to just figuratively disappear and we'll never hear anything from him again.
As much as I love speculating, we don't know squat. His name was partially scrubbed from the c2c site. He's not doing annual predictions, and now Snoron has officially come out and said (in a pretty tactless way) that Art was pretty much done doing shows.
We've heard nothing from Art, and tempting as those ham messages are, they're vague.
One good thing -- Snoory's tactless announcement could be a good sign. He didn't give details like 'Art is done for good with broadcasting, due to age, family, fill in the blank.' and if that were the case, Art probably would've said something on G2G.
The way things have played out, it feels like something is happening behind the scenes, George/C2C is giving as little details as possible and maybe we'll hear from Art in 2011.
