For what it is worth, the 718 GTS 4.0 configurator is available online now, and the MSRP is actually a bit lower than I had expected:

Cayman GTS 4.0 - $94500
Boxster GTS 4.0 - $96900
The engine in this GTS 4.0 is of course a detuned version of the 718 Cayman GT4 / Sypder. Makes for an interesting option within the 718 hierachy, IMO.
