When Red Dead Redemption 2 debuted, Sony touted PS4-exclusive content and promised we would hear "more details soon." A year later and even having gotten hands-on with the PlayStation 4 version of the game, we still have no idea what it is. [Update: The exclusives remain unclear, but we do know there will be a RDR2-themed PS4 Pro bundle.]

"We are pleased to announce that PS4 players get first access to earn select online content in the vast open world of Red Dead Redemption 2," said a post on the PlayStation Blog. "Check back on PlayStation Blog for more details soon and for all of the latest information on Red Dead Redemption 2."
