There is really not a lot of details about the upcoming Nintendo NX console. We were supposed to hear more about it this year but so far, Nintendo have not revealed much.
There have been a lot of talk about the Nintendo NX coming in as a hybrid console which means it might come as a handheld as well as a console because of that, there were rumors saying that the Nintendo NX game might not come in physical form but it looks like that is not the case.
GameStop has just revealed that the upcoming Nintendo NX console will have a physical media. It was reported that Paul Raines, the CEO of GameStop approached Nintendo to ask about their software format and have gotten the confirmation they needed.
