WOA is going to be called Windows RT, as of right now. Don't ask me why Microsoft decided to call it that, but that is what I have been told 2 days ago. It will be released the 3rd or 4th quarter 2012. I have asked Freescale about if they are going to support this platform. Freescale has not answering this question yet, but us developers would like to know this information as this gives us an idea on the hardware we need to get for development.
I would imagine that if they did support it, it would be for the i.MX6 platforms. As one of the prefered specs for use are dual processors. I also would like a definitive answer from Freescale about this also.
