But now, we know.
Super Mario creator Shigeru Miyamoto says it would take less than a year for third-party PC developers to port their games to Switch.
In declarations collected by the media Gamereactor, Moore stressed that "Well, as we have said, we are custom-building a Federation Internationale de Football Association version for the Nintendo Switch".
"That ease of software development has also been felt by Nintendo's internal developers".
Game fans are on their toes to have the all-new Nintendo Switch which is all set to be unveiled very soon.
Both of them hope that they will get to see people buying the Switch and then enjoying it for a long period of time, in the same way people used to enjoy Nintendo's earlier home consoles such as the Famicom.
"The Nintendo folks I think are making a great effort to reach out to third-party developers, which I think is fantastic", said Take-Two president Karl Slatoff.
One of the issues with the Wii U was a lack of third-party support.
The company's partnerships with mobile developers DeNA and Niantic have certainly been fruitful and Nintendo is looking forward to bringing more of its coveted IPs to the smartphone realm.
Miyamoto stopped short of claiming that Nintendo would use Unreal to make games, but the company is obviously de-emphasizing the importance of its own tools as the sole solution for building games on the Switch. Moore didn't even confirm if they were to launch a Nintendo Switch version of "Mass Effect: Andromeda".
Nintendo's support of Unreal Engine 4 was one of the first details we learned about the upcoming console.
Federation Internationale de Football Association 17 Winter Upgrades are expected to launch in four separate updates, the first of which is now expected to be released on Friday.
