Impossible, unless Microsoft buys Sony.
Even if they were giving away xbox for free it would be almost impossible.
Microsoft would have to launch at least 5 new single player masterpieces in year 1, which is impossible as we are already 9 months in, and nothing is even coming this whole year to beat Horizon zero dawn, god of war, spiderman, demon souls, the last of us 2, Ghost of tsushima, death stranding, etc
Microsoft could do it, example sea of thieves as a great opportunity but they made it online, it could have been be best pirate single player ever. Microsoft should have noted that playstation sells because they have plenty single player masterpieces, that's what xbox needs. Online is good, but we already have fortnite and call of duty for that, people buy consoles based on the single player exclusives.
