From the Let's talk R-10 thread on the Leica R forum:
The link points to a report summarizing a talk at LHSA's 2007 annual convention where "Herr Andreas Kaufmann, owner of Leica, spoke of their plans for the next generation R camera." David Young wrote:

But there is no doubt, that an entire new fleet of "R" glass is on the horizon. Hr. Kaufmann also indicated that Leica are moving fast towards a policy of having stock available for shipment almost as soon as products are officially announced. If this is realized, then we should see a new "R' camera and an entire line of new lenses, by the end of next year.Despite Mr Young's assumption that all of the 24 lenses are intended for the M and R lines, wouldn't a more likely explanation be that at least a few of them will have a 4/3rds mount?
