Google has added a new filtering option to software submitted to the Android Market, which looks to be a precursor to the download store arriving on Google TV. Developer Al Sutton spotted the change, which checks whether an app requires a touchscreen; that’s something you’ll find on an Android smartphone, but not on a Google TV device such as Logitech’s Revue.

According to the Google TV features page, Android Market access is expected to arrive early in 2011, opening the smart TV platform to a wealth of third-party apps.
