What are we thinking for the future of Minecraft?

Minecraft as we know it has evolved heavily. From a basic small indie game to a huge corporation run game. It's no doubt the game has gotten better. And with the new announcement of the mobs riding zombie horses, two new mobs that ride zombie horses, that wield SPEARS! SPEARS ARE IN THE GAME NOW?? This advancement intrigues me. But knowing there are some things Mojang will N E V E R add, where will the future of Minecraft go in 10 more years. 20?
