Sonic Adventure 3 coming?

Sega have previously confirmed that there is a Sonic game planned for release in 2013, and now Nintendo Life states that the game goes under the title Sonic Adventure 3 internally. Given that Nintendo Life is a Nintendo focused website they only mention, Nintendo 3DS and Wii U, but they note it is also coming to other platforms (likely PC, PS3 and Xbox 360).

Could we see a return to the roots of Sonic's 3D era that kicked off on Dreamcast almost 15 years ago? It remains to be seen...
