With all of the rumors of this tire having been discontinued (now that it is about my favorite tire) I called Dennis Kirk and ordered a new front for my '95 RT.

While I was jumping around the net, looking for a price for them to beat, I happened onto a listing for the new 2007 model Macadm 50e at motorcycle-superstore.com.
So, if the Macadam line was new and improved for 2007, then all of the talk about the "old" Macadam going away are likely correct, although a bit misleading. I went to Michelin's site, put in the info for my R100, and their tire selector listed the Macadams as the proper tire for this bike. This seemed to me pretty strong evidence that the tire was not being discontinued.
I called Michelin and they first said that it was being discontinued

and replaced by the Pilot Activ. I gave her my tire size and the rep said the Pilot was not made in those sizes.

Now I was confused. I was then asked to hold while she checked on something and after being on hold for a while she came back and said that only the 100/90-18 and 110/80-18

were being discontinued but the sizes I were interested in were still being produced and there had been nothing said about discontinuing the line.

Of course, I suppose, that could change tomorrow...
Sooo, the Macadam line is STILL my favorite tire, but I refuse to be baited into a tire thread and any such attempt will be split off and moved to the "Rants" section where I believe all tire and oil threads belong...
