Youtube served me this video on the start page
Which source is https://enfusionengine.com/ , it seems the page for their new engine opened some days ago.
An interesting point is this:
"The Enfusion Workbench also connects to our backend systems, including our own multiplatform workshop solution. Combined with this workshop, the Workbench also serves as a fully integrated environment for developing, packing, and publishing mods for Enfusion games. "
They will have their own backend and mod workshop solution, so it seems they will skip using Steam’s.
In some way they are offering too their first screenshots of Arma 4…
…because what, are we supposed to believe they created that big, detailed terrain with all those art assets just to put them as screenshot examples of the engine in a obscure marketing website? Nah, that doesn’t make sense. That surely is taken from their current development of Arma 4.
In fact they could have renderred whatever other thing if just wanted to test the engine, like something cartoony or a random modern city model. But that’s LOOKS LIKE the Arma style of the previous games.
