In the German version of the LFI magazine from November 2011 there is an interesting text in the "preview" section on page 74:
"Die Gerüchteverdichtensich, dass es bald NeuheitenvonLeica in unterschiedlichenProduktkategoriengebenwird. Wirberichten in dernächstenAusgabeundwarten, wennmöglich, mitersten Tests auf."
which basically means that LFI will probably publish some tests of a new Leica product in their next issue expected in December 2011.
My guess is that this will be the previously rumored Leica 50mm f/2.0 Summicron-M ASPH lens.
