Same here w/ Orbbec Astra-- I'm very weary of relying on a 3rd-parties (especially options that have a requirement to "phone home" in order to use on a new machine.)
I imagine whoever could make this process seamless could capture the most market share of whatever void Kinect is leaving...
I am agnostic when it comes to the actual hardware, the Astra Pro is an incredible low-power/low-complexity device but what matters at the end of the day is the software & development velocity
When it comes to software, there's another option (about which we should rightly be skeptical/cautious) Microsoft's Kinect site cryptically write: "Microsoft is working with Intel to provide an option for developers looking to transition from the Kinect for Windows platform. Microsoft will continue to provide support for the Kinect for Windows SDK via our online forums, premiere and paid technical support. As developers transition from Kinect hardware, Microsoft encourages developers to look into Intel’s RealSense depth cameras."
Unclear what "provide an option" means but perhaps that's a clue about migrating their visual gesture builder tool to work w/ the RealSense cameras...why not an Orbbec?
