SEGA has not thought about a future for Sonic Mania after Plus, says Sonic Mania was embraced by the younger generation

The following comes from a Famitsu interview with Sonic series producer, Takashi Iizuka...

Q: When you hear that the motivation for development is high enough, I expect a sequel.

Iizuka: The next project is called Sonic Mania ' (Dash).(Laughs) That was a joke, the project "Sonic Mania" feels complete issuing the packaged version "Plus". I have not thought about what to do with the series in the future currently.

Later in the interview, Iizuka reveals that a lot of younger kids purchased Sonic Mania, especially outside of Japan.

Thanks to everyone who bought the original Sonic Mania, we’re able to continue it to Plus, and we’re really grateful for that. There may be some impressions that Sonic Mania was aimed for people who knew of the Genesis-era games simply because it is a 2D game that feels like the past, but in actuality, people from a very broad age range are playing it.

Especially outside Japan, the highest user demographics of digital downloads came from grade schoolers. This time we’re selling it in a form and price that’s easy to obtain, so to those who haven’t got to play this yet, please kindly get this. I can proudly recommend this title to Japanese grade schoolers as well.
