Not exactly the question, but Fable is the Xbox exclusive I'm the most excited about by a long, long way. I don't care for the Horizon games, but that studio have serious technical chops. And if it's single player focused, and of comparable scope to something like Horizon: Zero Dawn? Oh my... It really could be something very, very special.
I have zero faith in Halo Infinite. 343 have made two utterly bland games, and aiming for something seemingly far grander seems like the worst idea imaginable.
