You can start off your July with a bang, as Sony has announced that there will be a July 2nd demo for Gran Turismo 6. You'll also have the opportunity to participate in the GT Academy 2013 competition, which will net you free bonus content if you submit a qualifying time. If you win the contest, you'll have a chance to quality for a Driver Development Program, as well as a chance to race a Nissan GT-R GT3 NISMO..
Truth be told, I haven't been in love with a Gran Turismo game since the third entry. My interest kind of waned in later years, and I really hope 6 can get that spark going again.
