Examiner reports on a rumour of a new realistic racing game from Ubisoft called The Crew - that is being positioned to challenge Forza Motorsport 5 and Gran Turismo 6. The Crew is apparently in development at Ubisoft Reflections (the old Driver outfit in Newcastle) and would be coming to PC, PS4, Xbox One and current gen consoles (PS3, 360).
Ubisoft Reflections is one of several studios involved with Watch Dogs, but given their racing pedigree it's entirely possible they have a second game in the works.
