No confirmation either way yet.
I am against pre-orders but if someone is giving you money blindly without even checking reviews of your product: at least you can throw them some carrot. Early access is actually a good way to do it. Plus you can test servers stability, keep an eye on early game-breaking bugs/performance issues that will not impact release reviews (which is smart to do). Honestly, ANYTHING that can lead to this game fixing any sort of bugs issues before release is welcome by me.
I will be there 17th too as I got Darktide from my wife as gift so I may as well take advantage of it. I will be happy to provide more feedback in hopes of this game being better and better.
I just really hope Fatshark will start listening to feedback more for Darktide than they did for Vermintide 2.
