Yes third parties would be stupid to not develop for both platforms, unless they use the ps4's full capacity (something that japanese devs don't usually do) or use exclusive features (dual motion/HD rumble for switch, analog triggers for ps4).
However I would not be surprized if devs switch from making ps4 games and downscaling to switch, to developing switch version first then porting to ps4.
