Sony's cloud-based music service, the aptly titled Music Unlimited, has been destined for the PlayStation Vita since before it was called a PlayStation Vita. Today, Kaz Hirai revealed during Sony's annual CES keynote that the service would be available on day one for PlayStation Vita users. Also of significance to the Sony product owners of the US is the confirmation of PlayMemories Studio, the leaked editing application first seen this past weekend. It will allow users to manipulate photos and videos directly through the PS3.
