I would argue the Switch looks to have the 2nd best true exclusive lineup (edit: coming out this year) at worst (PC + console isn't true exclusive). XBox One doesn't have a whole lot coming out you cannot get elsewhere, PS4 has a decent lineup (Nioh, Persona 5, Horizon off the top of my head), but with Zelda + Mario Odyssey + Splatoon 2 + Xenoblade Chronicles 2 they have a pretty solid first year. The problem being what will they have coming out year 2 to add on to that? Only so many dev teams at Nintendo and they are putting out a LOT of first and second party content this year.
