Rumours supporting development of a new Sonic-themed racing game have started swirling again this week, possibly with British developer Sumo Digital back behind the wheel.

Reports originally surfaced last week about a new entry in the successful Sonic & Sega All-Stars Racing series, with slides reportedly hailing from an internal presentation at Sumo appearing on resetera. While this immediately set tongues wagging, Sega's Aaron Webber took to Twitter soon after to confirm nothing was in the pipeline, seemingly putting an end to any speculation. 

However, things have picked up again over the weekend with Zappies, a British toy manufacturer, revealing to a German Sonic website that it's making products based on a new Sonic racing game due out later this year. What gives this report further weight is the fact that Zappies has made toys based on the All-Stars Racing franchise in the past, so they are in a fairly reliable position. 

Still, this isn't an official confirmation by any means, so add a pinch of salt to your morning coffee just to be safe. It's also worth mentioning that Webber's Tweet may in fact be accurate; he said Sumo is not making another Sonic & Sega All-Stars Racing game, which may be the case if the project is going under a different name, possibly with a new cast to boot. 

Sumo Digital has worked on two instalments in the Mario Kart-inspired racing series: Sonic & Sega All-Stars Racing (2010) and Sonic & All-Stars Racing Transformed (2012), both of which hit PS3, PC, and Xbox 360 among other formats.
