Detroit -- In the race to open Detroit's first permanent casino, hotel and entertainment complex, the locally owned MotorCity Casino seems to have gained the edge over its closest competitor, MGM Grand Detroit. MotorCity Casino, owned by Marian Ilitch, will swing the doors open on its enlarged gaming space June 7. MotorCity also has moved up the date on the ribbon-cutting for its 400-room deluxe hotel to September from late in the year.
