Is Rush passing the torch? Or just specualtion?

Please take this with the speculation that I did when it was told to me.  But I thought I might find some confirmation here.  A friend of mine who is a retired AM radio guy from one of Rush Limbaugh’s first affiliates told me that he heard Rush would be passing the torch next year, though he has not picked his replacement yet.  I’ve been listening to rush since the late 80’s and would be surprised if this was the case.  Maybe he is simply planning to reduce his time on the air.  Or the guy is fooling with me.
