The rumblings come from a Go Nintendo source who is said to be close to the matter.
Sonic Adventure 3 is said to be the internal codename of the project, and it may not stick come launch time. But still, would you like to see a new game made similarly to the classic Dreamcast games? Or is 2D still the way forward?
Either way the next Sonic game will be revealed this month. Read our full report on the announcement here.
Thanks Nintendo Life.
