don't worry, there will be lots of additional lens reviews in this section. However, the Leica section has no high priority internally, which means as long as their is more "important" review work to (for example in the Nikon section) this part of photozone simply has to "idle".
In addition, the amount of time the review team can put into reviews is limited in general (we all do this in our spare time) and unfortunately extremely limited currently in my case (due to my main job... again).
Nonetheless: two additional reviews are already in the pipeline for publication (Noctilux 50/0.95 ASPH and SLRMagic Hyperprime 50/0.95), the next two reviews after that will most likely be the Zeiss ZM 50/2 and the Leica Summarit 50/2.5. I also just finished the lab tests with the Elmarit-M 135/2.8 (interesting beast).
One note though: there is no plan to shift to the new M. The M9 currently is and will remain to be the test camera. From a reviewer's perspective, the new M's sensor doesn't offer much over the older Kodak CCD, not even in terms of resolution. From my personal perspective (as a user of the M9): the new M has absolutely no appeal to me, sorry
