it's useless write you prediction.
As i said, OF COURSE 3DS can be down, but said that is IMPOSSIBLE that will be up not have sense.
Impossible is perhaps harsh in some minds, but to me it really is. It was a similar case with the 2DS that was supposed to help the hardware be up yoy and yet it fell significantly despite the revision. A revision will not help a product line belonging to a market that is more or less going to disappear in its current form within a fairly short amount of time.
It was down by quite a bit in 2014; I don't see how it will follow that up with being up solely due to a revision (again; the 2DS was said to be the reason it would be up in 2014 as well), the console is turning 4 years old now and has received all its major software hits, I can't see a single reason for it to grow what so ever.
End of 2016 hardware sales:
Wii U: 15 million. PS4: 54 million. One: 30 million. 3DS: 64.8 million. PSVita: 15.2 million.
