Microsoft Windows 10 update `Redstone`

http://www.zdnet.com/article/microsofts-redstone-an-update-to-windows-10-due-in-2016/  Zdnet have a article up about the new (supposedly) update to Windows10, named Redstone. It`s got me wondering, is Microsoft Windows10 going to be the first free to download but pay to update OS?  Redstone is claimed to be a rather big update... why are they working on this now and not just incorporated into the release?....

Oh look now were moving into Minecraft code names for the releases . Is the next one going to be Emerald, Lapis or Diamond?
