Monster Hunte: yes it will have an impact, but as you noted, it's not portable on PS4, which will both reduce impact to Nin and reduce sales of mhw in my opinion.
Price: I'm amazed Nintendo got away with the orice but now that it's well established, it is not a big deal. The market understands the price and Nintendo can slash it any time if really necessary.
Software: this is the big one. As you implied, the definite known lineup is nothing special, ports and second stringers. If Pokemon gets out this year, great. If Metroid is out this year AND if it's really great (botw great), it can have an effect too, thou not as much as Pokemon or Zelda or Mario. Hopefully Nintendo has something amazing waiting in the wings, because neither game is a lock for 2018 yet and if Metroid is average or "just good", it will not be enough.
