Quite a few of these titles were already confirmed to be for 3DS; out of the list provided in the OP, I believe only Pikmin and Tank Troopers weren't already announced for the system or released on Wii U previously. Chances are, if NX is portable, then we'll be seeing most of the 2017 titles show up there as well.
So, no, it's not a handheld competing with another handheld. It's Nintendo trying to give us at least something to play until the release of a new console instead of pulling a 2012 where there was almost nothing to play until the launch of the Wii U.
