In a series of statements to AP, Leica UK denied any existence of the previously rumored new mirrorless system:
“Asked whether Leica plans to launch a more compact system camera than its full-frame M9, a spokeswoman said there was no such system on the horizon.”
On several occasions in the past few months (LHSA meeting, LUF meeting, tech support email) Leica representatives did mention the existence of a new system that will serve also as a R-lens solution. It is also possible that this project was canceled or put on hold.
