As far I know now, the linear transponder for Phase 4 is a subset of Eagle 
hardware so both are being pursued in tandem. I don't think that the choice 
of what will be launched will be up to AMSAT but up to the launch providers 
as decisions will have to be based on when they can provide space for us and 
what it costs.
