The developer of Minecraft is a mobile gaming company called Mojang, and they are exceptionally transparent when it comes to the future of their franchise. The creators see no end in sight, so they are working hard to provide players with updates and new features that those players really want from the game. Minecraft, like many other games, is technically always in development.
The developers will take what information they gleaned from the beta release to finalize the full release of the new Minecraft edition. When you play the beta version of any game, including Minecraft, the object is to test the features of the game while finding and repairing any bugs that might affect how players experience the game. If you already own Minecraft for Mac or PC, you can download and enjoy the game for free. The Minecraft Beta isn't the beta version of the original game, but instead it's the beta version of the iteration that's about to be released.
