Originally, the WT team were very forthcoming with their future plans for the Garmins on their Discord. They shared the state of their re-written FMS / nav system they incorporated into the CJ4, and were quite adamant that this system would soon find its way into the G1000/3000 and G3X.
That’s somewhat changed since about December. In the past couple of months, there’s been a lot of “there are big changes coming, but we can’t talk about it” (I’m completely paraphrasing here) when people ask about the future of their Gamin mods. They’ve been somewhat open about the G3000 which has had several feature updates over the past several months, but they’re saying nothing about the G1000. When asking about the state of the G10000, the standard answer is the single dev working on it is “tied up with other commitments”.
I’m REALLY hoping Asobo contracted out the Garmin work to the WT team - particularly their complete re-write of the nav system. It’s pure speculation on my part, of course, but seeing their close relationship with Asobo, I would certainly consider this to be in the realm of possibility. And it would explain the absence of their G1000 guy since December, as well as their NDA-style replies to questions about their mod.
One can hope, right?
