Here are Nintendo's total yearly shipments dating back to fiscal year ending March 1991. I chose that year to start as it was Nintendo's first full year of adopting their current fiscal year time frame  (April 1-March 31).

FY90-19.82 million

FY91-25.25 million

FY92-24.35 million

FY93-19.04 million

FY94-10.39 million

FY95-10.12 million

FY96-16.58 million

FY97-22.92 million

FY98-23.09 million

FY99-24.45 million

FY00-22.91 million

FY01-26.15 million

FY02-22.70 million

FY03-23.06 million

FY04-24.58 million

FY05-22.25 million

FY06-34.16 million

FY07-50.64 million

FY08-57.36 million

FY09-47.69 million

FY10-36.22 million

FY11-30.06 million

FY12-23.95 million

FY13-16.31 million

FY14-12.57 million

Some things to note are that from FY90-05, Nintendo shipments were pretty consistent at around 20-25 million per year. FY93/94 were very low however at around 10 million, this was due to NES shipments drying up (it was still selling very well in the early 90s despite SNES on the market), Gameboy was beginning to show a notable decline and wouldn't show notable growth again until the late 90s when Pokémon & Gameboy Color released, and even SNES shipments were low in the west due to overshipping in the previous 2 years, Nintendo & retailers must have assumed SNES was going to replicate NES success in America.

The DS/Wii Era from FY06-11 was a massive growth from previous Nintendo generations with FY07-09 averaging over 50 million per year. The last few years have been tough for Nintendo with the DS/Wii Era ending and 3DS/Wii U underperforming. FY13/14 are the lowest shipments Nintendo has had since the mid-90s with FY15 possibly being the lowest since the 80s.

Going forward, I doubt we will ever see them replicate the success of DS/Wii, however I wonder if they can return to the 20-25 million baseline they held for the better part of 15 years. What are your thoughts on them returning to those level of sales next generation?

I honestly doubt they'll b able reach 25 million in a fiscal year. The handheld market has shrunk decisively, not only since the DS days, but since the GB peak and the GBA days. The next Nintendo home console will most likely be up over the Wii U, but I don't think it'll be able to go further than a good 25-30 million (Which would be almost doubling the Wii U).

FY record is something mindblowing.

Damn... They need to release the NX fast because Wii U and 3DS are not doing so good.

The problem are smart devices seeping into broader demographics like children by becoming super cheap the last couple of years.

The iPad wasn't as big of a problem when it was the only real tablet available because it cost $500+. Nowadays I see little kids, families of them and each kid has their own tablet and they're sitting on a flight playing games for 4-5 hours of a flight. These are like $150 tablets. 

This is why I've said in the other thread, they need to accept that being no.3 in the console race is unacceptable. They cannot have a low selling console while having such erosion in the portable market. At some point you have to say enough is enough and fight for marketshare. Specifically I say they need to target Microsoft's share of the console market (battling against Sony may too difficult because Sony has their shit together quite frankly on the console side). 

The whole "we can have a crappy selling console because we're selling 15-20 million portables a year" strategy doesn't work anymore because they're not selling portables at that rate anymore. 

Dem numbers tho. {0o0}

FY16 is likely to be the first year since Nintendo started making portables (1989) that they will have sub-10 million hardware shipments too. It other words it will be the lowest hardware shipment in the company's modern history.

But we don't need NX, lol.

Of course not. We need more Wii U and 3DS, more Federation Force and Amiibo Festival. Until they ship 0 units they can't move to NX.

How have we got fiscal year 2015? Doesn't that end 31st of march?

FY2015 ended in march 2015. Currently we are ongoing FY2016 ending in march 2016.
