The whole "Microsoft will ruin Minecraft" idea has no basis in reality. contrary to popular belief, Microsoft is not Hitler, and don't enjoy stepping on your favourite games just for shits and giggles. They realize that if they fuck up Minecraft in a way a majority of players don't like, they will legitimately ruin their companies image, and it would be a PR nightmare. Now, I'm not an expert at running a huge company like Microsoft, but I have a good feeling this is what they're going to do. They'll basically end up throwing a shitload of money at Mojang, and telling them to keep doing what they're doing, or potentially Dev another game.
