To qualify for the Academy, gamers need to race a Nissan 370Z around a GT5 track fast. The latest game is due sometime in March, 2010.
"On 17th December exclusively via the PlayStation store, we will be launching the GT Academy 2010 Time Trial. The time trial will be the only way into this year’s Academy, and if you’ve got what it takes it could be the start of a life-changing journey," posted Penrose Tackie on the EU PlayStation.Blog. There's sure to be a lot of try outs then.
"The time trial features the stunning Nissan 370Z in two guises. Firstly a blisteringly fast, race-tuned monster and secondly an only slightly less fearsome non-tuned version." A top time must be posted before January 24th, 2010 to make the GT Academy 2010.
Most probably couldn't give a spark plug for the Academy, they want the demo. Sony has put up a trailer for GT Academy 2010, and it shows some Nissan.
