In an interview with Toys ‘n' Playthings, Sega's European brand manager Sissel Henno went on record with the news of fresh Sonic titles in 2013.
"Over the next year there will be a big focus on the expansion of [Sonic licensed] toy distribution across Europe. Similarly, we will also be growing the apparel, publishing and stationary categories. We will have several new digital titles launching as well as a new boxed game, so there will be plenty of opportunities to link marketing campaigns across games and merchandise," said Henno.
Given that Sonic Generations was one of the best Sonic games in recent times, we're feeling cautiously optimistic about the future of the blue hedgehog.
