I want to know the answer to the following question:
At what event was Kinect announced?
All the background I'm provided with is that "During their CES 2010 keynote speech, Robbie Bach and Microsoft CEO Steve Ballmer went on to say that Kinect will be released during the holiday period (November–January) and it will work with every 360 console.". Is that enough to answer the question?
Answer: no
