Sony has released a FAQ for the PlayStation TV, and within that details have emerged that the PlayStation Now beta will launch on both Vita and TV on October 14th. That date is when the PS TV goes on sale in the US. Meanwhile Europe will not get the PS TV until November 14th. Other than that the FAQ reiterates fact the device won’t be compatible with standard definition TVs due to the HDMI output, and the resolutions it does support include 480p, 720p, and 1080i. The PS4 remote play visual will be at 720p.
The FAQ also states that there will be a day one patch that will add new features, so you will be required to connect it to the internet to have the full experience. You’ll also only be able to associate one main account with the PS TV, same as the Vita. A Network Media Player will also be made available after launch so you can stream music, photos, and videos from other devices in your home. Sony kind of sidesteps in how PS TVs that were imported from Japan will be supported, instead saying it is best to purchase one from the market you reside in.
