No.
Is the Xbox brand fading? Yes, but not faster than the 3DS. The 3DS is on its last legs. After Sun/Moon it might get the 3rd Gen 7 game (Pokémon Eclipse?)
Or Sun/Moon 2, or Diamond/Pearl remakes, but I think they'll hold off on that until after Gen 8 is out on NX, (I assume.)
But that's really all the 3DS has left to look forward to.
Xbox One still has the Slim, Scorpio, Gears of War, And a lot of big 3rd party titles like GTA VI to look forward to. Now granted I don't think it'll finish close to where the 360 ended up and that Microsoft is headed toward another direction with PC, but the Xbox One isn't going away any time soon
