Why should they when they can do it from their own platform like Disney did after their 3rd party tryout?
Tech evolves, content is king.
Is that Disney thing actually taking off? I'm still buying their 3rd party outings, blu-ray, runs fine on ps3!
But true why should they, when suckers like me buy their system just to play Zelda and Mario every gen. Then wonder how good botw could look on some decent hardware :p (I played Botw for 170 hours on a 1080p projector. Switch had to sit in the middle of the room because the left joy con kept losing connection if the Switch was more than 2 meters away... crappy WiiU range all over again)
Tech evolves, keep up!
