Cougar-compatible handles? Now I'm REALLY interested,...
Don't hold your breath. I wouldn't trust Thrustmaster/Guillemot to make good on this. I know for a fact that before the Cougar was released, other grips were said to be released, i.e. F15, F18 etc... it never materialized.
So, I wouldn't rest my hopes on this.
Also, the Warthog HOTAS isn't as boxy because the whole electronics part is quite compact - from what I have seen on the T160000M - as the switches are located in the grip. It's good, on a side note I hope they won't skimp on the quality of the stick gimbal.
I remember that too. We were also apparently supposed to get an "RCS Pro" with toe brakes that plugged right into the Cougar, which clearly never happened.
Nevertheless, if I get the Warthog and it does have a better, compatible handle, I'd probably use it on my Cougar base for when a force-sensing stick better suits the sim in question.
That also means that the stock gimbals in the Warthog better be good, however...
