The product looks pretty developed and as someone that has always viewed the Pinion MGU as a complete turd, this one really looks like a home run.
They are saying release in 4th quarter 2026 so maybe some of the new bike releases scheduled for around that time, have already lined this product up in their development cycle.
There is also a rumor that it uses Shimano mounting pattern so could be a drop in for Shimano motors.
I will say that I borrowed a gearbox pedal bike once, I think it was a Zerode. It pedaled poorly but the rear suspension performance was other worldly and the silence was amazing.
