I will be really surprised if they don’t. Their ecosystem is still estimated to include close to 30 million people. No matter what fanboys say, this is a lot of people buying their games, purchasing DLC from their store, buying their overpriced accessories, etc. Not to mention that, for their streaming service to function, they need console hardware, as moving to PC servers would add an incredible overhead to their operations and eliminate any compatibility with Xbox One and Xbox Series games.
What I don’t think they’ll repeat next generation is the idea of having two different classes of devices—at least not with both being home consoles. Whether they choose to focus on the more powerful but less popular device, or the less powerful but better-selling one, only time will tell. Personally, I feel it’s going to be the former, with the latter being replaced by Xbox Cloud.
