Considering the 3DS is probably going to end up on par with last year, or lower if VGC is overtracking it again, I doubt next year will fare any better. This year we had some real heavy hitters for the 3DS, as well as a $129 model that was supposed to appeal to kids. Nintendo may choose to price cut, but it won't be by much. I'm guessing the 2DS will stay the same, but the 3DS will drop to $149 and the 3DS XL will drop to $169. Of course, price is no longer a problem for the 3DS (not since the drop to $169), so I doubt it will give it a huge boost.
So, yes, it will probably be ahead of the PS4, but it will be far from "domination." The PS4 should do at least 11M-12M. In 2015, however, I expect the 3DS will start to decline, while the PS4 will increase. So, 11M-12M for the 3DS, and PS4 14M-16M.
