Sony has opened a new section of the PlayStation Vita portal site. It's called "What's New about PlayStation Vita." Yes, that's the Japanese name. I'm not sure if they just forgot to put the title in Japanese, or if they're being "cool" by writing it in English.
The page will list major firmware updates, application releases and more. Its opening coincides with today's release of the system's 1.60 firmware, which adds a map app, video capabilities to the photo app and a few other features.
