SEGA Sammy has released a bunch of information about their fiscal year of 2017 and the coming year, 2018. In these reports are detailed steps that SEGA Sammy are taking to completing their Road to 2020.
One such route they are taking is with their flagship franchise, Sonic the Hedgehog. We know inside their report, they stated that both Sonic Mania and Sonic Forces performed extremely well with consumers.
That being said, SEGA Sammy also confirms that new Sonic titles are currently beginning preparation by SEGA. They also state that the upcoming Sonic movie will begin production and is on track for a November 2019 release.
Sonic had a rocky 2017. With the success of Sonic Mania and the mediocre reviews of Sonic Forces, it is tough to say which route SEGA will take Sonic in their rebuild to 2020.
However, fans are looking forward to a new Sonic racing game that will be revelaed later this year.
