Sky dimension

The Sky Dimension (otherwise known as the Floating Island Dimension or the dream world and sometimes referred to as heaven) is a work in progress by Notch. It "performs well, [but] looks ugly". It is now a confirmed update but the releasedate is not known. In a live webcast on the Swedish gaming site feber.se Notch revealed that the Sky Dimension would "probably be a dream world" and that when "you go to bed there is a certain chance that you get dragged into the dream world instead. Then you will be able to do it on purpose later on."

History
The Sky Dimension was first announced after Notch played Spleef against a men with the tweeter account called "Evil_Notch" (video is on twitter). It was probably made to be like a "heaven", since the "Evil Mojang" team declared the Nether to be "hell". The sky dimension was not completely confirmed until Notch released an update via Twitter stating: "And because PC Gamer made such a big deal of the sky dimension, I guess I'll have to finish it. Consider it confirmed."
