As first reported at Kotaku, it seems that Microsoft's big XBOX exclusive Crackdown 3 is facing another delay, this time into the next calendar year. From the report by Jason Schreier:
First planned for November 2017, then delayed to 2018, the long-troubled open-world action game Crackdown 3 will now be out in 2019, according to two people familiar with the game’s release plans. It’s an unusual move and another blow to Xbox’s already weak first-party lineup for the rest of 2018.
It's an obvious blow to the ailing first party exclusives for the XBOX One. Microsoft has not yet replied to questions about this report, but we'll know soon enough as E3 is next week.
