When was this announced? I know they gave the release date for early access on 12/12/17, but nowhere did I read or hear that it is now officially an XBO console exclusive. If this was official, MS would’ve blasted this everywhere. Is this just more of MS’s deceptive advertising, and they mean “console exclusive for 2017” like what they pulled with Rise of the Tomb Raider?
