They have, just had an all day conference earlier this week for win 10 as we are bringing it into our organization in 2016. It's lost the tablet touch and is completely overhauled. I'm actually going to like it.
They completely copied apple's way. Windows 10 will be it; PC, phone and tablet (albeit a slim version). From 10, we will .2, .3 etc. it's actually a nice OS. The only thing that's garbage is their reliance on cloud (RE: pay me every year/month and I'll let you use my software remotely, along with your info, which I now own).
