Microsoft official approved this "disclosure", perhaps they are “testing the waters”?.

"Surprisingly I got the all clear from Microsoft to show this cancelled pitch material," Wright wrote in the description. "We did some proposals for Halo Wars 3, I had to introduce space battles into the game style, as well as having your capital ship as your home base, to prep your ground forces."
The description has since been removed and replaced with "Halo Wars 2 additional work done for Creative Assembly for Halo Wars 2. Property of Microsoft." Wright has given no explanation as to why the change was made.

A new collection of concept art reveals details of a Halo Wars 3 pitch that featured space battles and XCOM-esque base management.
Halo Wars 2 managed to capture the feeling of Bungie’s famous franchise but wasn’t that intense of a strategy game. A handful of art, shared by Creative Assembly concept artist Brad Wright, offers a glimpse into a pitch for Halo Wars 3 that would have expanded the scope of combat and added additional strategy elements.
The pitched artwork helps break down a base management system where players could customize and outfit their main spaceship with various rooms. Players would be able to hover over them to reveal their stats boost, as well as zoom in to explore in more detail. These rooms could be upgraded to affect ship performance in space battles. It highly resembles the way players expands their base in XCOM, with new rooms offering benefits to soldiers and defenses.
While this particular pitch was canceled, it offers an intriguing look at some of the options Creative Assembly were considering for the next game. Maybe some of it will carry over to a third Halo Wars, if that ever happens. I’d love to manage my own giant, Spartan-filled space base.
You can look at all the art here. It’s awesome.
