"plan?!?!?" ....   *chuckle*

Ummm, from my perspective, the "plan" is to retain the two circuit
simulators as part of the suite.  Both have their places.  Al will
continue to improve Gnucap, and ngspice will also (more) slowly
evolve.  Folks can use either one, depending upon what works best for
them.

As for the new netlist backends for Verilog-AMS or VHDL-AMS to feed
Gnucap:  They will appear as soon as somebody steps up to the plate
and creates them!

I suggest you play around with both Gnucap and ngspice, and see which
one suits your purposes.  I believe Gnucap still accepts SPICE syntax
netlists, so you can netlist using spice-sdb and then use either
Gnucap or ngspice for simulation.
