Yes, I've read reports on this a little while back and It seems Microsoft are branding "Windows 10" for It's future releases.

Although details are sketchy at the moment, It seems like future releases of the OS will be similar to that of an upgrade- keeping "Windows 10" Intact, but perhaps adding a version-type (number, build etc) Instead.

You never know, though.

Down the road Microsoft could start to build another operating system if the reports of Windows 10 being the last major release.
