Release dates for both Injustice 2 and Mass Effect: Andromeda have supposedly leaked after an error by Microsoft. IBT reports dates for both games were spotted on the Microsoft website, which you can see a screenshot of below. 

In case you can't read the print Injustice 2 is marked for March 28th and Mass Effect: Andromeda has a date of March 31st. 

Even though the source is reliable, it is possible that both dates could just be placeholders for the actual dates...although why not just put a question mark if it's a placeholder? We will keep you updated should we hear any official confirmation.
