SEGA possibly teasing Sonic Dash for Android
The picture shows a rather rotund version of the blue blur along with the simple message: "Soon." So what could it be? My immediate thought was a mobile game of some sort, and then it was brought to my attention that Sonic is somewhat shaped like the Android mascot.
Could it be Sonic Dash for Android devices? Currently, the game is available for iOS devices only, but perhaps that's changing "soon."
