This is the tip I received anonymously:
I can confirm the rumor about the M9 release later this year. It will be released on 2009/09/09 and will be full frame! It’ll cost about â‚6000.
I am surprised from this news – I don’t know if Leica can pull this one out: they have to release the S2 and the R10 first I believe. I will try to get some more info on this unconfirmed for now rumor.
