Good Vibes Gaming recently got to interview Takashi Iizuka, with the topic being primarily on Sonic X Shadow Generations.
One of the last questions GVG asked him was the possibility of a potential Sonic RPG (Good Vibes Gaming did of course mention Sonic Chronicles but noted that it was a BioWare project) on modern consoles and PC. Iizuka replied of course that he would like to make a Sonic Team-developed Sonic RPG before he retires, but was quick to point out that no concrete plans are currently in place.
