Just as the SXSW Gaming panel was closing, Sega had time for one final tease:

The only information given out is that it is 'not a sequel to any of the previous Sonic games'. That means that despite that very familiar R it is not a Sonic R remake (because there is definitely a car in there) or a new All-Star Racing sequel is in the cards. We will hopefully find out more about this title on March 22nd or at the very least when E3 2018 comes around. More importantly: we'll know if there's a Nintendo Switch version of this mysterious game.
