Those who like Trophies on PS4 may well use them to brag to their friends about how they've got more Trophies in their virtual collection, and for those people the latest update should be of interest as, according to PlayStation's Twitter: "Starting today, Trophies will sync much more quickly so you can brag to your friends as soon as they're unlocked!"
You could do this manually before, but now this is much quicker, so you can instantly rub your friends' noses in it if you beat them to a particular Trophy. What other features do you want PlayStation to include in the future?
