Reddit user theConzor posted to the Minecraft Pocket Edition sub-reddit about how he attended Wired's Next Generation event in London. Johan, the main developer for Minecraft Pocket Edition, was there to share how he started as a game developer and his current job at Mojang. The reddit user went on to say he was able to talk to Johan after the event, and even got to hug him (lucky!). "I thanked him for his hard work adding new features to MCPE and said, on behalf of /r/MCPE that I was very grateful for all the updates and am looking forward to 0.8.0! He also reconfirmed infinite worlds for 0.9.0!" he said in his Reddit post.
Minecraft Pocket Edition having infinite worlds has always been talked about, and was held off several times due to time and device hardware restraints, but it looks like come 2014 Pocket Edition players will finally have it. Curiously enough, infinite worlds is something that isn't on the XBox 360 Edition, and probably never will.
