This is not out yet, it's expected 2nd quarter 2016. But Razer is coming out with a tech heavy webcam called Stargazer.
Razer Stargazer
Captures at 60fps in 720, or 30fps at 1080.
Automatic noise cancelling.
Dynamic background removal. (so you don't need green screens any more, it can remove any background on its own)
3D scanning so it can port scanned objects into Unity or directly to 3D printing. Or even your face to put yourself in a game.
Facial/gesture recognition.
Dual array mic.
Unlock your computer using Windows Hello, launch applications with a wave of the hand, or even play gesture-enabled games.
It may be worth waiting for.
The features are a lot more interesting for a Twitch streamer than a cam model. US$200 for a static webcam? It's probably no better in practice than a C920 for most models.
