Well updates were here long and even up to now. Also everyone wanted full w10 experience in mobile device. Will it be foldable one or futuristic glasses, doesn't matter much in short time, as long as OS is full W10.
Full x86 windows on a mobile device will be an interesting proposition. It will be difficult to properly display a lot of desktop apps. Maybe some form of "magnification spot" could be used when trying to click buttons etc.
