Now, maybe I did miss this product announcement, but there appears to be a new Leica X1 digiscoping adapter (model 42331) shown at Leicainnederland:
The pictures of the adapter appears to be taken at Photokina or some other photography show, but I do not remember seeing any online coverage of this product. Leica did indicate in the past that they will develop a series of accessories for the X1.
Update: here is another picture of the adapter being displayed at Photokina from twitpic:
A quick Google search shows that several websites are already selling it for £100.00.
There is already an existing digiscoping adapter for the D-Lux 4:
