The force feedback in the triggers was indeed new, but the "haptics" (I think it's basically a low frequency loudspeaker) were already present in the Switch controllers, and before that in iPhones under the name "Taptic engine". Unfortunately the Xbox controller still lacks these "haptics", as well as gyroscope and accelerometer, any force feedback etc.
