Will group policy editor be included in the standard edition of Windows 10?

[Windows Central Question]

GPEditor did not exist for home win 8 users. I find myself needing it often. For that reason, I was going to upgrade my win 8.1 to win 8.1 Pro, BUT...with Windows 10 on the horizon, will my Pro key transfer to the newer OS? I'd hate to get boinked out of a hundred bucks. Thanks for your help.
