Viral marketing can be pretty effective, and Sega is no stranger to the tactic. Recently on their Twitter and Facebook pages, Sega has posted the above photo and nothing more. For those unfamiliar with Sonic Dash, the photo is definitely a screenshot from the game, with Sonic in the mold of the Android robot. All signs point to this being a subtle announcement of Sonic Dash coming to Android devices, which is a welcome choice in my opinion. The more people who can experience a great auto-runner, the better, I say. What do you think?
