Another Sony Google TV device is apparently on its way, as shown by a certificate posted on the Wi-Fi Alliance website.

The new Sony Google TV is the successor of the Sony NSZ-G7 (pictured above), available since last year and which has been recently updated. That is probably the reason why Sony has decided to go with product number NSZ-G8 for the new device, although the company has not officially announced the product yet.

Unfortunately, apart from the Wi-Fi certification, no other details, such as specs, price or release date are available at the moment for the new Sony Google TV. Still, with Google I/O 2013 less than a month away, there’s a serious chance for it to be shown there.

Google TV has failed to make a big mark so far, but manufacturers, such as Asus (with its Cube available now), Sony, LG and even Chinese company Hisense (which made a good impression with its Pulse) seem to be keeping their faith, releasing new products.

Do you already own a Google TV device or, if not, do you plan on purchasing one? And if so, which one will it be?
