Despite being the little brother of the bunch, Minecraft: Pocket Edition has become quite the sales juggernaut. The game stays atop the charts on both iOS and Android, and sales have surpassed 5 million. Not bad for a premium app in an age where most mobile gamers refused to pay for anything. Now, Mojang could sit back and relax, but the developer is already working on the next update for Minecraft: Pocket Edition.

The next update to hit Minecraft: Pocket Edition will bring the game up to version 0.5.1. It’s not the mythical 0.6.0 update that will bring a lot of new features to the game, but the latest update will feature a number of additions that will make any Minecraft fan happy.

For starters, the update will finally add signs to the mobile version of the game. You can check out a preview of what they look like on Johan’s Twitter feed. Clouds and bluer skies are also being added with clouds being only available on fast devices.

The biggest addition to version 0.5.1 is gravity. Now certain block types will fall when losing the support of blocks beneath it. I’m sure some players enjoyed the gravity defying blocks of the Pocket Edition, but the addition of gravity is just one more step towards making Pocket Edition just like its console and PC cousins.

As for the big update coming with version 0.6.0, the team has revealed some of what they’re working on. First, caves will be added for those with faster devices as the feature seems to cripple older devices. The update will also probably add stone brick slabs and stairs alongside Redstone and Redstone powered objects. There’s a chance that these could show up in 0.5.1, but it’s more likely that these features are being saved for the big 0.6.0 update.

So, when can you expect to see the 0.5.1 update hitting your favorite mobile device? Mojang is planning on having it out by the end of the month. If not, it will be out at the beginning of February. Until then, keep mining your anti-gravity blocks while you have the chance.
