I think Odyssey is a safe-bet, judging by the sales of previous 3D Mario titles and the reception the game has received so far. It's actually had far more views online than Breath of the Wild, 23 million for the original Youtube trailer versus 11 million for Breath of the Wild.
Breath of the Wild I'd love to see hit 10 million. Nintendo themselves said in their financial briefing they think this could be the series' biggest seller yet, so that's a good shout.
Splatoon 2 is more difficult to gauge, but I think it'll be closer to 10 million than 5 million, certainly. I also think the Smash Bros analogy is a good one.
