Even sim racing, is only now slowly getting ffb and rumble in pedals. Fanatec has been the only brand to offer it directly on pedals for a long time, and ofc there's the basically diy solution one dude sells I shared a pic of, and now Simagic has rumble modules for their p1000 pedals, and Simucube is just now starting to ship out their active pedal to fulfill preorders.
Haptic seat pads are making a comeback to mainstream with NextLevelRacing's HF8, and buttkicker is also becoming more and more popular.
It is only a matter of time before rumble or haptics in racing pedals becomes a must have feature for flagship products all sim peripheral brands put out, and then with the massive popularity of MSFS, and 2024 going to be an INSANE game, people who are exposed to flight sim after being hardcore racing enthusiasts will start asking where tf the ffb and haptics are for that, having been used to it from racing.
The trickle down is sadly very slow it seems, and who can hardly blame flight sim game devs for not implementing features when no hardware exists to utilize the features save for people with 30k-500k commercial training rigs who do their own in house stuff anyway.
Places like news outlets giving the Rhino some exposure will definitely help, and at least module makers seem more responsive (as in priority wise actually have the time to implement sooner) than sim devs directly.
I think the best thing we can do, in addition to continually reminding ED, and IL2 devs etc. that FFB exists and we want features, is to keep an eye on any new sim that gets announced, and try to get devs for those on board as early as possible. Combat Pilot, a recently announced WW2 Pacific flight sim is a great example of such opportunities.
