>>35152616>How does the engine has any bearing on when it's revealed? Why does "it's using a new engine" translate into "they have to reveal it sooner?"The game has already been announced. We know from the August 2017 GameInformer video interview with Masuda and Ohmori that the games were still in their earliest stages of development at that point because they outright said it. They also said they were waiting for Christmas 2017 to see how younger players would use the Switch so they could decide how to design the core gameplay.
There's no way that the games will go from their core stages in Christmas 2017 to finished in late 2018. People are banking on an April 2018 announcement to tell them that the games will come out in late 2018. Sure they can reveal information whenever they want, but considering the first look at the games is normally done in the same year as the release, it doesn't make an April 2018 'first look' to be very likely.
