Sony's on top of the PlayStation 4 system updates, it seems, as they've just announced that they'll be releasing patch 1.51 later today to address some minor issues. Don't expect anything outright noticeable, but there may be some small things. For instance the patch will make it clearer when you're downloading a game and the game's patch at the same time. Otherwise, just expect some general stability improvements.
Some may recall that developers over the past week have been passing the blame for early game issues onto Sony for their late changes to the OS, like with voice chat. EA even made a fairly damning statement about how all of their games would have issues until Sony fixed their problems. Hopefully this is the patch we're looking for?
Also, that UI update may not seem like a big issue, but I know that at least I had problems before. I'd notice that a download had completed for a game so I'd try and start it, but the system would bug out as apparently I'd only downloaded the game's patch, rather than the game itself. I was forced to download and reinstall a couple games because of that.
Obviously we'll never know the full breadth of the 1.51 update, but nevertheless it's good to see Sony on top of things and pushing out important updates as fast as they can. Cheers, Sony! Helps they have a million fans out there excited for everything they've got coming down the pipeline.
