I agree, but I don't think this is a problem. Switch-> Nintendo games.
PS4-> everything else.
Perfect match. As long as Nintendo keeps making high quality games that sell well everybody wins. Honestly, the less multiplatform games are released on the Switch the better, as the weak hardware could pose a limit to third party games...well, unfortunately it's a limit for 1st party games as well (xc2), I just hope that japanese devs won't start scaling down their games just because they want to release on the switch.
