Project Toad will be an add-on to the RACE07/GTR Evo base, similar to what SimBin did with the STCC title. Like STCC, it will improve and enhance the base game as well as iron out the odd bugs still left in the system, add new cars, new tracks and a new level of fun and competitive racing. It's not a lot of concrete info, but SimBin promised there will be more details shortly.
