It is not a secret anymore that Sony is actually speeding towards PC gaming. This year alone, we have seen many games such as Uncharted: The Legacy of Thieves Collection and Spider-Man making the leap towards PC platform.
According to the latest news, we may see another name joining to the list but it is too early to speak. Kazunori Yamauchi, lead for Gran Turismo series, confirmed in an interview that he thinks that the legendary racing series could be a good fit for PC platform.
Obviously, it would definitely not be an easy process to go through, and he also said that too. Especially running the game in 4K/60FPS native quality requires narrowing down the game to a certain platform for now, so there is a serious challenge if one wants to port the game to another platform.
