Microsoft announces the Proteus Controller, a gamepad for Xbox gamers with disabilities

Is this mean t as a replacement for, or in addition to the Adaptive Controller kits that were in the news a few years back? This seems like a logical end point for that program (i.e. I remember the adaptive controller looking relatively unpolished in comparison to this product). Another commenter pointed out that the actual cost of the adaptive controller is greater than the sticker price would indicate since you need to add peripherals to the base $99 controller to achieve functionality, but hopefully it's still a feasible option for folks that maybe can't quite swing a $300 purchase.
