Theme support is also coming to Sony's PlayStation Vita handheld system. PlayStation 4 theme support was unveiled at a Sony Computer Entertainment Japan Asia (SCEJA) press conference in Tokyo. According to Sony, "themes are among the most requested features from PS4 owners, so we're eager to offer them." Sony said theme support will be implemented via two system updates: v2.00 for PS4 and v.3.30 for PS Vita. Sony did not announce a specific release date for these two system updates, saying only that they would arrive "this fall." In addition to the PS4 theme support, Sony also said PS4 owners will be able to watch PS4 live streams using their PS Vita via a new app. This app, called "Live from PlayStation," will let PS4 owners watch live streams from Twitch and USTREAM directly on their PlayStation Vita handheld. Considering the growth of Twitch live streams and viewers in particular, this functionality is bound to be popular.
