The Steam page is up now.
No date is listed other than "Coming soon".
I'm betting February.
There is a link to wish-list it but not a pre-order link.
Oddly, graphics is now listed as either Win10 or Win7 (not Win8.1). Microsoft released tools to enable developers to get DirectX 12 games to run on Win7 but not Win8.1. I think Cyberpunk did this.
The developers had Strange Brigade run on either Win10 DirextX 12 or on Vulkan. Epic games store requirements claim that Vulkan is supported but only for Win 7 and no mention of Win 8.1.https://store.steampowered.com/app/694280/Zombie_Army_4_Dead_War/?curator_clanid=32806657This comment was edited on Jan 26, 2021, 15:00.
