Kinect 2 will be so powerful it will be able to lip read!
The Kinect 2, besides having the ability to “see” much closer (20-40 cm!) than V1 will be so powerful it will (rumor has it) enable your program of choice (albeit using Windows 7/8) to lip read, detect when people are angry (or otherwise), and determine in which direction they are facing.
Having gotten into chat bots when I was looking for a C# “chat” library for my “talking head” animatronic projects (I have since pretty much been reduced to using an avatar-based system since servos are just too damn noisy…), this looks to be really cool development for a natural spoken word input (as opposed to using a keyboard, or fairly low res Windows voice recognition) chat bot interface. I have more recently used the Kinect V1 for person tracking and it already works better than any other sensor (sonar, IR, etc.) in the price range (<$100), but full on lip reading would be quite remarkable indeed!
Should be a real boon for anyone making chatting robots that interact with real people in RL (like a kiosk bot, as opposed to on a web page over the internets).
