While Asobo has contracted WT to redo the G1000 NXi, G3000/G5000, and GNS430/GNS530 my understanding is that they are explicitly not doing any further work on the G3X code for Asobo, and that the old mod has also become abandonware which will not receive further updates. (I hope I’m wrong on this and misread some posts.)
So if people want improvements to the G3X systems over what’s in the base system, some 3rd party or community mod will have to do it.
