One thing I know with absolute certainty: if Ed Boon says something definitive about a game of his, it must be true. After a rumor broke earlier today that the long-awaited Injustice 2, the sequel to the DC-focused superhero fighting game, would be coming out on March 28th, Ed Boon took to Twitter to quite simply say "Injustice 2 is not coming out March 28."
The rumor started after a NeoGaf user noticed an Xbox Live rewards page that listed Injustice 2 as releasing on March 28, 2017. This website also listed a release date for the upcoming Mass Effect: Andromeda as March 31, as well as a March 30 release date for the upcoming Ubisoft title South Park: The Fractured But Whole.
While Bioware has yet to comment officially on this rumor, they told a Twitter user yesterday that they are aiming for a release date in "Spring 2017," which indicates that they do not have a set-in-stone date. No to mention that, if Ed Boon confirmed the Injustice 2 release date was wrong, it's likely the Mass Effect: Andromeda and South Park release dates are not to be trusted.

All of these games are still slated for 2017, but it's not going to be as soon as this Xbox Rewards page indicates, unfortunately.
