To answer the question from the last (and I believe now closed) TK thread about XM, the answer is yes.
From XM's press release today:
WASHINGTON, Feb. 15 /PRNewswire-FirstCall/ -- Tony Kornheiser -- sportswriter, columnist, ESPN commentator, humorist, and author -- will be heard nationwide on XM Satellite Radio starting March 5.
Kornheiser's new radio show, originating from Washington Post Radio (WTWP) in Washington, D.C., will air from coast to coast on XM's sports talk radio channel XM Sports Nation (XM Channel 144) Monday through Friday from 9 am to 11 am ET. Tony will also host special shows exclusively for the XM Radio audience on a regular basis.
I said this last year when they actually devoted an episode to the Evil Monkey. When they're actively tying up running gags (in this case, Brian writing a book), you get the sense that the end is near for this show.
