The additional verbiage is enigmatic at best—I would urge you to make your own estimation if you're interested. Apparently either Leica is working on a replacement for the R system, or intends to have the upcoming digital S system replace the R system, or something else. Evidently a dealer, SH Photo, has bought out Leica's remaining stock of R9 cameras and R lenses.
The R system is Leica's 35mm film SLR line. It was born as the Leicaflex in 1964 as a response to the runaway popularity of Japanese SLRs from Canon, Nikon, Pentax and others. The "R" appellation appeared as of the R3 of 1976, a camera based on Minolta's XE-7. In 1980, the R4 appeared, based on the Minolta XD-11. Subsequently, Leica's relationship with Minolta cooled, so the same body style remained, with successive updates, modifications, and refinements, until the introduction of the R8, designed by Manfred Meinzer, in 1996. Although Leica had floated a public stock offering to fund its development, the R8, one of the very last all-new manual focus SLRs at least among higher-end cameras, was a commercial failure.
Leica's SLRs were virtually always conservative to the point of anachronism even when new, and although they had their adherents, even diehard Leicaphiles never quite gave the line their wholehearted allegiance, especially after the Minolta influence appeared. However, the point was really always the lenses, the finest of which were arguably among the best ever made for 35mm photography. An entire (long!) article could be written on the lens line, chronicling the various lensmakers who contributed R lenses (Zeiss, Schneider, and Minolta at least), the Leitz family's inital adamant resistance to zooms, the Mandler designs, and the standouts in the line. Used Leica R equipment, which never held its value like the M cameras and lenses did, remains the best way for 35mm film enthusiasts to achieve Leica quality on a budget.
ADDENDUM: Erwin Puts has written a beautiful brief obituary for the R9, from the heart.
Featured Comment by Rubén: "Leica is developing a R10 camera with autofocus lenses. Leica has stated this many times. The basic electronic design of the S2 will be shared with the R10 and the M9: processor, motherboard, interface...this is not a secret.
"Why is Leica terminating its stocks of R lenses?
"I think Leica stopped R production time ago, and now only a few items remain unsold in Solms warehouses...Leica is announcing no more manual focus R lenses will be produced...that's all. So, if you plan to buy new R gear, buy it now.
"I am sure the future R10 camera will have a R mount, with additional ROM contacts for AF control. Simple and direct compatibility with manual focus R lenses."
Mike replies: Of course you might be right, Rubén, but I'm not seein' it, I have to say. The global economic situation has changed quite a bit recently, which might have an impact on past plans. Just because something is said to be "in development" doesn't necessarily mean it has to become a product or a product line people can buy. Also, as stated, your assumptions don't make much sense to me. I would rate the chances of a new film AF camera to be something close to zilch. If you accept this, then you accept that the "R10" will also be a digital SLR. If that's the case, sticking with the R mount doesn't make sense to me except in terms of backward compatibility—backward compatibility with the manual-focus R lenses that Leica just dumped and is not going to continue to make.
Leica's principal innovation recently is the S-sized 30x45mm sensor—which I think is a very good idea, by the way. A digital "R10" with a 24x36mm sensor would compete with all the other FF cameras, exactly what the S system is intended to avoid; a full-frame R10 would also probably poach sales from the S2. But if the R10 is to use a smaller sensor, and as long as Leica is designing all-new lenses anyway, then why not design it from the ground up and really do it right?
I'll tell you what I think, and this is purely a guess—I'm going to bet that any future "R10" (or non-S-system digital SLR) will be a Four-Thirds standard camera. That would allow Leica's DSLR offerings to be tiered into small and large sensors; it would allow the camera's buyers to use existing 4/3 lenses from other manufacturers, meaning Leica could make a few key lenses itself but not have to start from scratch and develop an entire new self-contained line, an enormously investment-intensive proposition (especially when it's just done that very thing with the S-system lenses!); and it would address what will be the key shortcoming of the S system, which will be its lack of long telephoto lenses. It makes more sense all around—and, if the S-system move is any indication, Leica is making a lot of sense lately.
Of course, I've got no crystal ball.
