Why don't we let Bob himself tell us what he's thinking?
"I’m kinda taking it year by year, but it’s getting close. . . . I’m not gonna try and go as long as Vin [Scully] – until I’m 80-something years old. I still enjoy it. But, like I say, it’s becoming more and more difficult to keep up with everything – even with the availability of sources that we never had before, like the internet and all that kinda stuff. . . .
"I don’t think I’m ready to say that I’m done yet. But, let me put it this way, it’s not going to be too far off.”
Bob Miller (Nov. 2012) (http://mayorsmanor.com/2012/11/kings...t-coming-soon/).
Let's let him tell us when he's ready.
