I think I may have connected some dots this evening. The Sony Headset Companion app has specific presets for the following list of games: Assassins Creed Syndicate, Uncharted Collection, Destiny, Until Dawn, Batman Arkham whateverthelatestoneis, Bloodborne, and Far Cry.
Every single one of those games have also appeared on the Rewards Catalog. I know Uncharted, Until Dawn and Bloodborne are all exclusive to Sony so that explains those games, but his could be a potential hint that Assassins Creed Syndicate will be appearing on the catalog soon as well.
Or MAYBE... MAYBE... I'm really f****** bored.
