How much time left does the 3DS have?

[PAOerfulone]

2 years tops.
Next year will be it's last big year with a large number of titles coming out, some of them very highly anticipated.
Fire Emblem: Fates
Pokemon Z
Youkai Watch 3 in Japan, and depending on how good the 1st game does in the West, possibly Yo-Kai Watch 2.
Bravely Second, Mario & Luigi: Paper Jam, throw in Federation Force for extra , although that may be pushed back to 2017, I'm willing to predict.
Then 2017 will be a mostly dead year, with the only possible big titles I can see being released for it at that point being Pokemon Gen 7.
Whatever they might have had planned for the 3DS at that point, same with whatever they had planned for Wii U, I think has been moved to NX.
