XM/Sirius Ending PGA Tour Radio Deal?

Steve Elling offers up several items of note in his Up and Down column but this one is the most depressing about the solid PGA Tour Radio Network and rumor that XM/Sirius likely will not be renewing:

According to a source, the PGA Tour has been paid $4 million annually for the radio rights fees, and the celestial broadcaster isn't going to re-up. Moreover, it doesn't want to pay the salaries and travel costs for the folks who handle the live tournament broadcasts, either. Consequently, last week at Disney, the tour's radio crew had no idea whether they'll be back in 2011, and if so, in what form or fashion. Pardon the pun, but stay tuned.

$4 million does sound excessive considering the audience size was likely quite small. Ah but the demographics, i know, I know.
