Actually there aren't 'years on his contract', it's up in 2010 (next year). Although truthfully, his health is so poor, he doubtful will survive to complete even that.
He's now barely able to get thru the 2-3 segments he does each week. Which is why
the show profits have fallen so drastically. When he returned last October, after being absent for months, he promised a 'gradual return.' But that hasn't materialized and won't. I mean, let's face it - he's a human being, not fine wine - it's not like he's getting better with age! ABC/Citadel now has a real dilemma beyond just sentiment for the old man. They're starting to lose money. That'll guarantee a swift 'retirement' for the broadcaster who expected to 'go on forever.'
Either way, the end is near..............
