I think this is the most solid prediction i have ever seen.

Is this for worldwide?

150k
100k
80k

First Week: Below 110'000 but above 90'000.
Second Week: Below 90'000 but above 75'000. (Could hold well in the second week since MK8 comes out so late in the week.)
Third Week: Below 70'000 but above 55'000.

I think, if Nintendo releases games enough, it could flat line at about 55k. However, that's if Nintendo does something right. Which would be a very odd case.

100K
65K
50K

650k first week.
2:450K
3:200K
4,5,6,7,8,9 : 50K+

then drop until holidays.

Well, pre-orders are nearing 200k so that equals already 200k sales. This is what I think.

1. 250k
2. 135k
3. 90k

Then after that, having an average of 40k a week until holidays. It seems a bit extreme now, but sales will jump sky high.... at least the first week the game is out.

Geez guys, this is hardware, not software!

Week 1: 100k
Week 2: 80k
Week 3: 60k

Well they do have that deal with Mario Kart 8. EU/UK will see a huge increase for sure, it will be tamer on this side of the ocean

First: 150 - 160k
Second: 100 - 125
Third: Levelling off at 60 - 80k per week until the 31st of July

Putting them in line to break 7 million and be in the range of maybe 7.2 or 7.6 million units sold, while PS4 will likely hit the 8+ million at that point because of Watch_Dogs.

In the summer, expect 3DS/2DS sales to increase dramatically because of Smash Bros, and expect Xbox One to hit 6 million units sold by end of June.

Crap ton of predictions, who knows what will happen post-E3 for all the consoles

My prediction based on intuition XD:

1st - 100k
2nd - 75k
3rd - 55k
