With several delays already under their belt, Slightly Mad Studios have recently updated the FAQ for the Project CARS website to reaffirm that they’re still committed to Wii U and PC release. If you’re unfamiliar with the current status of the game, after obtaining help from publisher Namco Bandai, two delays of the game have been announced since fall 2014.
When is Project CARS released?
Mid-May on all platforms in Europe and the US with Wii U and Steam OS versions to follow later in 2015.
