Ahead of its September 7th New York City event, today Sony announced via its PlayStation blog that PlayStation Now will be available on Windows PCs. The PlayStation Now service was introduced last year and offers users the ability to stream a library of 400+ games for a monthly membership fee. Sony also introduced an all-new USB wireless adapter for the DualShock 4. PlayStation Now will be launching in the coming weeks in Europe with a North America launch shortly thereafter. The DualShock 4 USB Wireless Adapter will be available for purchase next month for $24.99.
