According to the online portfolio of Romanus Fuhrmann, a voice actor for the critically-acclaimed Sonic series, we might be able to expect Sonic Mach2 to be released later this year. The project was listed on Fuhrmann’s website (pictured below) under the 2015 header.
According to the website, Fuhrmann will be reprising his role as Orbot for the upcoming title, which will hopefully be released by Sega before the year is out.
