I don't see any reason why the expected new Leica lenses should NOT work on 
film! 

AFAIR, the release of "several" lenses was announced (or at least 
rumoured). With a crop factor of x1.33, it is quite easy to imagine which 
"new" focal lengths could be expected.

left: trad. focal lengths
right: corresp. new focal length for "digital" M lenses

50 -> 37.5
35 -> 26.25
28 -> 21
24 -> 18
21 -> 15.75

Lets go through:

- A 37.5mm lens is not very likely. But a new, fast 40mm? - to counter 
Voigtlander's 1.4/40 Nokton? Would be a more and more popular 
focal length for film, and a 53mm for digital. 

- A new 26.25mm does not make sense, so the "traditional" 28/2 ASPH 
Summicron could be the new "standard 35 digital prime" (a 37.3mm in fact).

- New 15mm (instead of 15.75), 18mm and 21mm lenses seem most likely to me. 

I could expect two of the last group and the 40mm. All ASPH, all fast. And 
all expensive...

<backbite mode>
Another possibility is, that Leica makes a 37.5mm but calls it "40" and a 
26.25mm and calls it "28" - like some older 50 Summicrons that had 52mm 
effectively... </backbite mode>
