Hard to tell if the sum of two poor results is a success. WiiU was horrible. 3DS was mediocre. But the market is shrinking and there's always some overlap between home consoles and handhelds clients.
If NS actually replaces 3DS and sells 80M, I will say those sales are ok (not really a success and not really a flop).
80mil is not really a success? Think about that for a minute.
I have. If NS is Nintendo's handheld for the years to come, it's basically responding to 2 markets.
WiiU was a disaster. Nintendo never did so poorly. 3DS was definitely not good. I think any other Nintendo handheld did better per year. How can the average of 2 bad results be good? Because, if NS does really replace 3DS, the sales must be devided by 2 in order to fairly compare to other generations. When was the last time Nintendo's home console + handheld did 80M? The 8th generation, of course. And before that?
Yeah...in that case, 80M won't be a success.
However, if NS does not replace 3DS, then 80M is quite an achievement. Not as good as Wii, but still definitely a success.
