Just how these pics were made and exactly what they mean isn’t known.
Since Gran Turismo Sport was officially announced, we haven’t gotten a whole lot of information as to what to expect from the game. The developers, Polyphony Digital did confirm during their announcement press conference that this game will not be a full Gran Turismo 7 but it will be bigger than most of the games we’re used to seeing that don’t carry a number behind them.
During the developer’s recent holiday party, it appears they did at least hint a bit at some new cars that are going to be in the game, as well as some locations. The company had some very high resolution photos hung up for all to see. While the pictures seemed to be a bit too high res to actually be screenshots we can assume these are concept art and teasers of what we will see in the game.
It seems likely that these were indeed the work of the developers because they have the GT logo in a corner of each one. GT Planet is speculating the photos are composite works that are made to look that much better and get people even more excited for what you might indeed see in Gran Turismo Sport when it is finally released. Gran Turismo Sport doesn’t have an official release date yet but it is expected to hit store shelves sometime in 2016 for the PS4.
