To tell you the truth I strongly believe it will eventually come to consoles too.
Many "minor" games have been released on several different platforms like wasteland 3, wich was created by the mind behind the original Fallout: Brian Fargo. Wasteland 3 was crowdfunded, and it did not stop the game from being accessible on Xbox, Playstation, Windows, Linux and MacOS.
I give you another example: "Desperados 3" - a real time tactic's game that resembles "Commandos", in fact I would say it's a truly successor to that beloved franchise, and was made by a team of "6" (six) core developers. It was launched on PC, Xbox and Playstation. It also received enhanced versions made to take advantage of the PS4Pro, Xbox One X and Series S|X.
So yes, let's hope Jagged Alliance 3 becomes a huge success, so there would be no excuses to keep it from the current gen consoles.
