ORIGINAL STORY 3/2/14 10.16AM: An unannounced Sonic the Hedgehog game is in development for PlayStation 4 and Xbox One, as well as Wii U, a new report suggests.
Sega previously announced it was working on another Nintendo-exclusive Sonic title - the final part of the publisher's three-game Sega Nintendo alliance deal which has so far comprised Sonic: Lost World and Mario & Sonic at the Winter Olympic Games: Sochi 2014.
There's no mention of the Nintendo-exclusive game on the franchise's roadmap - which raises questions as to whether the 2015 title is the same project, expanded to PS4 and Xbox One.
Wii U has seen a number of its exclusive games turned into multi-platform releases in response to the console's lacklustre sales.
The product sheet also contains new details of Sonic Boom, an upcoming 3D-animated TV series due to launch this autumn.
Sega declined to comment on the report when contacted by Eurogamer this morning.
