Sony has detailed the new features to be added in firmware update version 3.70, which will be available "soon." For PlayStation Plus users, Automatic Download is transforming into Automatic Update, which will automatically back up save game data. You'll simply need to set it up for the game in question in its options menu. Trophies will auto-sync as well.
Also new with 3.7 is a new recommendations feature for the PlayStation Store which allows users to send messages about a particular game or video to PSN friends. In short, Sony has made it more convenient for you to help sell its products. For no pay. Kickass, right?
The XMB will also receive a new category called TV/Video Services, which is where you'll find all of your apps for services like Netflix and Hulu Plus. New apps can be downloaded from there while a My Channels folder keeps it all in one place.
Those with 3D TVs get some added support as well, but its pretty minimal stuff. Java-based Blu-ray special features will now play in 3D and new audio formats are supported. 3D digital photos (MPO format) will also now be viewable in your photo gallery.
In addition, Sony confirmed that the version 6.60 firmware update is coming soon to the PlayStation Portable as well, though the changes it brings are "minor."
