Sony executive deputy president Kaz Hirai announced at CES that the PlayStation Vita has sold 500,000 units in Japan. The mark was set in three weeks of sales, which is a week longer than it took the 3DS to selling a half million.
In additional PS Vita news, Hirai noted that they want a Netflix app to come to the Vita when the system launches, or soon after. One thing he did confirm is that the Music Unlimited from Sony will be available on at launch for the portable console.
