Slowly but surely, we're moving into a true cross-play world.
When cross-play becomes the norm instead of the exception, that will truly be a great day for gaming. And while we're not even close to that yet, Minecraft fans are at least getting a taste of the future.
Earlier this morning ahead of this year's Minecon, Mojang announced that — provided you're playing on the subscriber Realms service — Minecraft would have full cross-play support, between consoles, PC and mobiles, all at once.

The Realms part is the obvious catch. Realms servers support up to 10 players right now, although I wouldn't be surprised if that limit is eventually expanded. If you want to enjoy the true shenanigans of Minecraft, however, you'll probably want to stick to the original.
Update: The Minecraft team has provided Kotaku with an official statement:
We are working toward a future where Minecraft players can play together using the devices they want. As we announced at E3, we are working on bringing cross-device multiplayer to consoles next year in addition to the cross-device multiplayer we have today on mobile, Gear VR and Windows 10. The image tweeted was an error – while we are working on enabling our players to play together on the devices they prefer, we don't have further to share at this time.
