Der folgende Test stammt aus einen GameSpot Interview mit den Tekken Produzent und Direktor Katsuhiro Harada...

KH: Well, you know, it's always a challenge. For example with Tekken 7, because we use Unreal Engine 4 that allows us to first bring the game to PC, something we've never done before. Unreal Engine was great because right away, we could get the graphics to a certain level quality the game was running fairly quickly. But it's not something right out of the box we can program and it's done. There are a lot of things that people don't realize, we have to reprogram on our side to make it work well with Unreal Engine. That was just for the current hardware, so you can imagine that for Switch. Especially at launch, that's something that wasn't a viable option. Some of the core components have to be handled by the engine, so I guess, as time goes on, maybe we'll see more of the adaptation of the engine to the Switch. Maybe we'll see methods to make a lighter version of the game that's easily portable to that platform. At the moment, that's not necessarily the case.
Actually, we haven't really done much research into how much it would take to do that, yet, as we're still working on trying to address certain areas of the game or to add features for the current platforms that people are interested in. So, we're not even really aware yet of how many people would actually want a Switch version of the game. ...
