I have not seen an official announcement so I have no idea if it’s real or a mock-up. But if it’s real, I want it. Especially if it works with Camtasia, Expression Encoder 3 and Vegas Movie Studio Platinum Edition 9 and above. My screencasts will never be the same and it’s looking like it’s time to buy my green screen.
[UPDATE] It's official now. See http://www.microsoft.com/hardware/digitalcommunication/ProductDetails.aspx?pid=008.
