Someday soon, you'll be asked to update your PlayStation 3's software. When you do, you'll be ready for the PlayStation Store's new "recommendations" feature. Consider it a new way for you to be sold things via the console's PlayStation Network.
It's not cross-game chat or software emulation for PlayStation 2 games or auto-syncing Trophies—currently the top three most requested features on the PlayStation.blog Share site—but maybe it'll turn you onto something new and undiscovered. Expect PS3 firmware 3.41 any minute now, along with PSP firmware 6.31.
