Doesn't matter; analog or digital it will still be limited to 12.5 kHz, 
and eventually 6.25 kHz.

Many systems are already using lower deviation so it's not as much of an 
issue; last time I fired up my service monitor on the Columbus system, 
for example, it was showing 2.5 kHz deviation (half the typical 5 kHz).
