Nintendo and Microsoft created an advert together to show Sony how its done
Even though console manufacturers are expected to be bitter rivals, since E3 2018 ended with the whole Sony cross platform debacle taking flight, Microsft and Nintendo decided to take a swipe at them by creating a minecraft playtogether advert.
The intention of the Advert isn’t designed to highlight the platforms that are playing together. It’s designed to highlight the platform that isn’t.
a variety of the world’s biggest games at present ie. Minecraft, Rocket League, Fortnite etc. all support some form of crossplay but Sony continues to refuse to allow PlayStation consoles to join in when it comes to it's console peers.
Sony has yet to respond to the Nintendo/Microsoft teamup marketing campaign.
