In fact, a series of Beta sessions starting in early February have been confirmed by the developers in a forum thread that's only visible to members of the Insiders Programme.
Our larger Age III: DE closed beta sessions will be dedicated to multiplayer, matchmaking, and the way the game feels when you play with others. We’ll be kicking off these multiplayer closed beta sessions starting in early February.
Our plan is to ramp up by first including fans of the original Age III, so the February session will include a limited number of invitations; however, we’ll be making room for more Age fans and inviting a larger audience come March.
The post goes on to say that there'll be Beta sessions dedicated to the game's campaign as well, though these will be active at a later time. Age of Empires III Definitive Edition Beta will run on both Steam and Microsoft Store, in case you were wondering.
Age of Empires III originally launched in 2005. While it didn't have quite the same outstanding success of its predecessor, it still reviewed favorably at the time.
