Sony Exec says GT6 is coming to PS3 this year (NEW UPDATE: Sony refused to deny the rumors)

The engine is there, the car models are there, they spent years constructing it, and they didn't stop after the game was released (check GT5 version 2). Now all that's left is re-use the engine, add more few cars, make another GT game, slap the number 6 on it = profit.
