Nintendo of America president Reggie Fils-Aime recently spoke to CNET about the upcoming smartphone title Super Mario Run, as well as the company’s future in mobile gaming. He also acknowledged the shortages of the NES Classic Edition in addition to revealing that Nintendo, as of now, has no plans to release classic NES games on mobile devices.

On the topic of Super Mario Run, Reggie told CNET that the mobile game would not see a release on the upcoming Switch:

“Development for Super Mario Run is different than development for Nintendo Switch [the company’s all-new Wii U successor, coming in March 2017]. With Switch we’re going to have a variety of input devices, a variety of ways for you to interact with the game. Here, it’s all the screen. So it’s a different type of development challenge. But at the core, our developers are looking to create content that you really can’t get anywhere else, you can’t experience anywhere else…that’s a core philosophy that’s going to continue.”

Next, he did acknowledge the shortage of NES Classic Editions with the following:

“Every day there’s more going into the retail channel. The overall level of demand is certainly greater than we anticipated, that’s why we’re suffering through the shortages out there in the marketplace.”

Despite the success of Pokémon GO and Nintendo’s hopes for Super Mario Run, Reggie said that there are currently no plans for bringing NES games onto mobile devices:

“Candidly, no, without a fair amount of modification. And this hearkens back to the questions that we received maybe five years ago saying, ‘Nintendo, when are you going to get into mobile?’ And at the time, it was positioned as, just take all your legacy content and just put it on mobile. The fact of the matter is, to make a great mobile game, you can’t do that. You need to think about the input device. You need to think about, how is this going to be sticky?”

Finally, though Super Mario Run will not get a version for the Switch, Reggie didn’t completely rule out the possibility of a future Apple TV release, saying the following:

“You know…we haven’t even launched Super Mario Run yet, so we haven’t even thought about those types of applications, but again, what I would say is, we developed this to live on these kinds of screens, and to be played in this type of experience, and we think that’s what it’s best for. Let’s see what happens after the 15th of December.”

Super Mario Run will release for iOS on December 15th, and Android devices sometime in 2017. The Nintendo Switch is slated for a March 2017 launch, and more details are expected to be revealed during an event in January.
