Sega has moved to clarify that Sonic Boom, the spin-off transmedia Sonic 'universe', will not replace the more traditional titles developed in Japan by Sonic Team.
Sonic Boom was unveiled in New York on Thursday and encompasses Wii U and 3DS games, a CGI television series and a new range of toys.
The Sonic Boom game - the third and final title in a Nintendo exclusivity deal - is in development at California based Big Red Button Entertainment, the studio founded by ex-Naughty Dog veterans Bob Rafei and Dan Arey in February 2008.
Most significantly, it features a "bold" and "brave" redesign of Sonic's classic cast of characters. But for those less impressed with the series' new look, Sega insists it will continue to release other titles featuring "Modern Sonic".
Speaking to CVG at the unveil event, Big Red Button's CEO Bob Rafei suggested that Sonic Team-developed titles could release alongside the new Sonic Boom "branch" in the future.
"Modern Sonic is still a key component," he said. "He sits side by side with this product and delivers a much different sort of experience.
"As you can see in the game, it's a much different experience than a typical Sonic game. We want to capture that and draw in new users and also try something new for the Sonic franchise."
"But obviously modern Sonic is very important to us, he's such an iconic character, as is the gameplay associated with him from Sonic team.
"So we want to make sure that that's maintained as well. I'm sure you're going to see stuff from both sides going forward."
Sega of America producer Stephen Frost claimed in the same interview that Boom was simply a piece of "brave" experimentation for the franchise.
"The way I see it, it's just a branch of the franchise," he said.
"You see franchises that have been around for a long time go through this process where they look to explore other opportunities, that's what this is. It's a really great, bold move on Sega's part. It's a very brave move."
