Don't think so. Apparently, the devs already said in WD that they intend GKs to work more as an allied force, or a standalone force that needs some help from allies to really become powerfull.
So they are just going to go back to the way it was in codex: Daemonhunters in a way. Missing serious anti-tank firepower or scoring bodies that you'll have to grab from other codexes.
They might still add the odd dataslate later on, but I doubt there will be unit entries in the codex that "mysteriously" have no models yet released. That got them into the legal pile of horse manure they got into recently... Ironically, one of the few mistakes GW has learned from... :D
So instead of the Mary sue mess that ward created it's going to be awesome again?
