Scott,

Not being a cmake master myself, it is currently not my personal plan, but if 
we have GDAL committers like Dmitriy to champion the effort and other 
contributors to help, I imagine it can be considered at some point. 

I see that "friends" projects like proj or libgeotiff have both build systems 
currently (actually 3 with the nmake one...). On the other hand, I think 
MapServer did the switch in one step ( 
http://mapserver.org/fr/development/rfc/ms-rfc-92.html ) 

The downside of having an interim period is that during it there's additional 
maintenance needed, but given the big number of potential GDAL dependencies, 
it seems unrealistic to have cmake conf feature-full and production ready, in 
a single step, if it stays in a branch.
