Do we know when .
We don't. We have such a long list of planned updates for the core GSX program, that we'll be busy releasing updates for the next 5 years, at least.
The first planned update is an overhaul of the Pushback, which is probably the most used/useful feature in GSX.
I think our strategy should be quite clear: every year or so, we take a core basic system in GSX, and overhaul it entirely, exactly like we did for the refuel system, which was quite weak until we remade it from scratch. So, the refuel had its chance, now it's time to look at the pushback.
We'll eventually go back at the fuel at some stage, but we don't have any idea *when*
