This new video seems to tell us so! Near the beginning of the video, you can see crosshairs popping up over the ennemies while classic Sonic makes his way through the levels. Does this mean it is possible to obtain the homing attack at a later point in the game or is this a 3DS exclusive feature? Does this destroy your hope in a new good Sonic game or is it a minor inconvenince to you?
Oh, and 10 points for the person who finds out what Anime the header pic comes from.
