Well as i seen from articles in the internet about Windows Phone 8.1,it might not have everything mentioned in that concept but it already have some amazing stuff like Notification center or cortana which already promise something really good.
Interesting but we're talking Windows Phone 10 for a lot of that and maybe even WP 11. Unless the new CEO, whomever that turns out to be has this vision for the phone, it will be a while before that level of cool shows up.
