My prediction would be that the only future games to hit 1 million will be Xenoblade, Mario Maker, Zelda and possibly Star Fox (that one'll probably depend on how well it turns out).
Of those titles, I think sales will go:
1. Zelda (2-2.5 million)
2. Mario Maker (1.5-2 million)
3.Xenoblade (1 million)
4. Star Fox (0.75-1 million)
