History has shown that older systems will stay around if they are 
still useful to the ham community.  CW is a perfect example, and AM 
still exists in niches.  Similarly, analog SSB and FM will continue 
to exist and be used on air for decades.  Furthermore, the next 
generation of radios are likely to be software defined, so there will 
be no problems maintaining backwards compatibility with the modes we 
enjoy today.  If the radio doesn't have the mode we want, we will be 
able to either download a firmware upgrade or Google for the source 
code we need and install it ourselves.
