It's really hard to tell. First week depends on release date and how many Wii U owners will actually get it, which will be pretty low. Does it launch with the Switch or is it a Summer/Fall release?
As for lifetime, this is a game we have to expect very long legs, not only from quality but also timing. It will probably be the only Zelda game until AT LEAST late 2018, and the majority of new Switch owners will get it or Mario with the system.
I think we will get a near Splatoon "surprise" (but with a fairly better FW). When I make this type of predictions, I like using ranges:
Assuming it's a launch title
FW - 1.1 million to 1.6 million (500k to 800k for Wii U)
Launch window title
FW - 2.2 million to 3 million (400k to 600k for Wii U)
LT - 6 to 8 million (1 to 1.5 million for Wii U)
Bet with bluedawgs: I say Switch will outsell PS4 in 2018, he says PS4 will outsell Switch. He's now permabanned, but the bet will remain in my sig.
