Call me cynical, but I believe that Minecraft have not made such a huge update dedicated to such a random thing for no reason. It's also perfectly placed at the point where people are starting to actually panic at the alarming rates that bees are dying. So, Minecraft may use this as an opportunity to start some campaign work or charity for bees, which is a good thing! However, there must be something in it for them; that's how business works. So it's a win for everyone! The bees live, Microsoft gets a heavier pocket, and most importantly, we get to mindlessly admire and play around with bees to our hearts content. Go bees!
