I'm confused on this decision, really. They know that a lot of players, at the moment, plays GT5 and Forza at the same time, having both consoles. If PS4 comes out without a GT release, while Xbox brings the next-gen Forza, a lot of players may decide to buy the Xbox instead of PS4 because, being honest, Forza Motorsport is a great game, you may prefer GT, but you can't say it's a bad game. In short, they made a bad marketing decision in my opinion. They better work hard on a GT game on PS4 soon, let's say max in 2015, or this decision can really put the PS4 in a bad situation.
