Nintendo talks having cross-play on Switch, “trying to be more flexible as a company”

It's obvious why Sony aren't doing crossplay, because they have the lead and the biggest and most active network of the 3. They still want to keep the whole 'my friends have a PS4 so I'm getting one' thing in tact as it's a major selling point for a console with so much momentum and positive mind share. It's not consumer friendly, but that's why they're doing it.

Sony only has the biggest single network. The others combined are/will be bigger so it's not a selling point for a game like Minecraft and won't be for other games in the future. Hopefully more 3rd parties support cross-play and prioritise updates/DLC for the biggest combined userbase.
