From the ZDNet blog:
Google quietly launched Google Reader specifically designed for the Wii last night — the new interface even makes use of the buttons found on your Wiimote. On my initial digging, I cannot find a similar interface designed specifically for the PS3 browser.
To try the new interface in your current browser if you don’t have the Wii, visit http://www.google.com/reader/wii.
