What gives you the confidence to guarantee this? Nintendo has never made a cross gen 3D Mario game, yet you are so confident they will do it this time you can guarantee it?I garauntee you…any big 3D Mario/Zelda/DK/etc game they reveal and release in the next few years…is going to run on the OLED/Lite Switch.
The only big games that Nintendo has ever made cross platform were Zelda games, and these games were also heavily delayed, not originally intending to be cross gen. But now everyone thinks Nintendo is gonna make all their big games cross gen from now on, I guess because Sony is doing it?
