The next digital body coming out is the Leica M8, supposedly due in October. US dealers already taking orders. Specs are somewhat similar to the R-D1s but the price is about US$5000 iirc. The digital Ikon has been talked about for a while but is vaporware as of now, and I think for quite a while. Don't know where your dealer got his info from but it's not very accurate.
IMO, a used R-D1 would be a better buy. A simple firmware upgrade will miraculously transform it into a R-D1s. The upgrades are purely software based.
