I'm going with a mil on Wii U, and 5 mil on Switch, so 6 mil overall LT.

Switch: 6.5M-7.5M (LT) 1.5M-2M (FW)
Wii U: 1-1.5 million (LT) 500K (FW)

Some of you are getting a bit carried away.
11-13 million lifetime is extremely unlikely; the highest selling Zelda games are Ocarina on N64 at 7.6 million, and Twilight Princess on Wii/GC at 8.7 million.
The series may be adored by critics and Nintendo fans, but to get to the 11-13 million range you need the kind of enormous mainstream appeal that Zelda just doesn't have.

low fiirst week predictions, especially if this releases in the summer. got to imagine like all Switch owners are picking this up

People knocking other people's predictions yet the attach rate on Wii U for first party is higher than GC look at Mario Kart 8 plus Switch being a hybrid platform means that both portable and console userbases are on the platform, as optimistic as some predictions are it's not that farfetched tbh as TP sold near 9m with out the portable side of the userbase. BOTW will be not only on two consoles but available to portable players as well that's a massive factor it has over previous games.

The portable base won't help enough to get it to 11-13 million; A Link Between Worlds only sold about 3 million, and that came out when the portable market was considerably healthier than it is today.

According to whom? ALBW is on 3DS which if you haven't noticed is the current portable market, I remember when people thought Smash wasn't going to sell that much on portables as well, BOTW is a far different kind of Zelda game to what the portable  players normally get as well it's a massive jump for them.

3DS is the current portable market, but ALBW launched in 2013, and mobile has continued to chew into the portable marketshare since then. Not every 3DS owner is going to get a Switch, (kids these days play on tablets mostly) and not every one that does is going to get BotW.

Ahh the old mobile chestnut reminds me of the PS2 era when some humourously thought that Facebook games were actually going to replace console and PC gaming it's always a good laugh, we've been hearing about mobile for 5 years now guess what it'll never replace dedicate portables get over that. 2013 is only 3 years ago so drop this hilarious notion that now is different from back then because if your argument had any ground Pokemon Sun and Moon wouldn't be tearing things up now like it is, ALBW sold the same amount as Spirit Tracks which was on a platform with a far higher userbase.

Every portable gamer from both 3DS and Vita has only one choice of platform to get after 3DS and that is NS, kids still have dedicated gaming platforms as well because tablets and phones can't replicate a number of gaming experiences.

3DS won't even sell half of DS and will be Nintendo lowest selling handheld besides the Virtual Boy, Vita won't sell even a quarter of PSP. The decline is real.
