Expecting the handheld NX to receive new Monster Hunter games (even if we are talking about PS4/NX multiplats), when the mainline series was 3DS exclusive ever since 2011 and hunting games are significantly more popular on handhelds is far, far more reasonable than expecting full on PS4 exclusive mainline titles.
Your post doesn't make any sense in the context of this thread.
This won't happen. Maybe there will be an HD port for PS4 ... Verendus said something about MH on PS4 IIRC.
