How many million sellers will the Switch have after a year?

[SuperNova]

With Zelda, MK8D, Splatoon 2 and Mario Odyssey it has four guaranteed ones this year.
I Feel like between 1-2 Switch, ARMS, Xenoblade 2,  DQ11 (if it comes out this year on Switch) and unannounced titles chances are that it will have 5-6+.
