The patch notes for the update, which can be found here, are minuscule and reminiscent of Nintendo’s regular balance and performance updates: “This system software update improves system performance.”

What exactly it improves, Sony doesn’t say. However, the download for 6.51 takes up 463MB, so it seems to be an important patch, even if it isn’t a clear one. What stands out about the lack of clear detail or intent for this patch is how much more substantial the previous update, 6.50 was.

Regardless of what it does fix, the update doesn’t deliver on Sony’s promise of introducing the option to change PSN online IDs sometime early this year.

Sony did test a beta of the option last year for PlayStation Preview Program members that’s still ongoing. Yet it was full of bugs and potentially serious issues. One ResetEra user posted the cautions given to beta users after the program was rolled out:

You may lose access to content (including paid-for content) that you have acquired for your games, including content like add-ons and virtual currency. You may lose your progress within games, including game saved data, leaderboard data and progress toward trophies. Parts of your games and applications might not function properly, both online and offline. Your previous Online ID(s) may remain visible to you and other players in some places.

Many users did experience problems with lost progress and deleted DLC, which might be why Sony has yet to fully roll the option out.

Whenever it does make its way to all PSN members, the first name change will be free, but subsequent name changes will cost $5 each for PlayStation Plus subscribers and $10 for everyone else.

Sony has had an interesting and mixed year already. On the one hand, the company is making some intriguing and potentially positive changes, such as skipping E3 and implementing its own methods of delivering news to its fans. Yet at the same time, it’s also tightening control over how games are distributed and remaining silent about things fans want to know.
