Spanish magazine Nintendo Acción has confirmed in their latest issue that a Sonic game is on the way for Nintendo 3DS.
The small piece (Google Translated) states:
Just at the end of this issue, Sega confirmed to us that a new Sonic is coming to 3DS. And not just talking about the next Olympic challenge, with Mario, but a new unique product.
Whether this game is an exclusive 3DS title or the much rumoured 3DS version of Sonic Generations is anyone’s guess. Hopefully SEGA will reveal all soon or at E3.
