More important is to see where switch will maintain after splatoon 2.
First it kept at 40k, but declined to 20k after Mario kart.
Hopefully, it will keep at 30k+.

Next week would be very interesting. Ps4 and 3ds(that are now close to 30k) with dq11 would receive a sales bump and be a great competitors to switch.
I think the 3 will be above 40k, would be an amazing week.

Well the numbers don't really matter for Switch right now. Every single last Switch being made is being bought immediately. So 20k or 40k is just however many Nintendo ships to Japan. Likely it will be back down to 20's next week because they used all the stock they had been holding back for Splatoon launch, which was 99k. Switch numbers ain't gonna go up until Nintendo can start making more, which better be soon or else they'll miss out on a lot of money!

Amazing Switch and Splatoon 2 sales!! (I thought Splat2n would do like 800k but I guess I was being too optimistic)

Great numbers for both Splatoon and the Switch

i think nintendo switch sales will reach 5 million unit at the end of 2017

in japan of course 

All I see is sad children who have stood in line for hours and couldn't get a Switch while units were held back for the Splatoon launch. SAD.

I seriously doubt that...

Its only sit at 1.2m at the moment, and they have less than 5 months left,

the most important, 3DS is still strong in Japan.

Hardly they will have enuf stocks for 5m in Japan alone.

If it was full year, plus no supply shortages, yes. But not by the end of 2017 and not with supply shortages.

Yup
