If you look at how much it took to launch the MM for example, which was basically an altered M9:
then it's easy to see that developing a digital rangefinder from scratch will not be possible 'on a budget'. It nearly tanked the Epson photo division before. Leica is just lucky that this niche product fits the scale of their operation, and that the price points are, although very high, considered fitting the reputation of their products.
The good news these days is that digital rangefinders are available on a budget: I'm seeing M8's locally for around €1000 now, and M9's for just under €3000, not all that different from new aps-c and full-frame dslr's.
out of curiosity, the R&D budget.. does that include the employee's wages?
