I told you sales would be below 20k this last week ;)
Anyway, I do think the sales will go up over the next weeks, but too slow to beat 2015. Still, with Ginei Ibun Roku#FE at the end of the final week the year should end on a high note (and give next year a head start in sales with it's push), but I fear that it won't suffice. Unless it's Indie offensive this ending of November (Year Walk, Runbow, Affordable Space Adventures, Swords and Soldiers 2, Tiny Thief and FullBlast, all releasing beween today and November 25. Oh, and a new Taiko Drum on 26th) will do wonders, but I doubt that.
2016 should become a good year, possibly the best one unless NX steals it's show. The higher baseline should carry over and avoid those nasty sales drops the console had this spring. Coupled with a head start from the sales from Ginei Ibun Raku #FE, we will possibly have a reversed situation compared to this year: A strong start with possibly a weak middle and finish. It all depends on the games to come and what happens to NX
