In answer to the prayers of the braying masses on Twitter who are bombarding @Jeb_" href="http://twitter.com/jeb_">Jeb with “When is 1.8 out?” tweets, we have http://whenisminecraftout.net/ that answers the question beautifully in a single sentence.
Long version? Minecraft 1.8 will be released as a pair of updates. Part one being the version taken to PAX (with some additional bug fixes) *hopefully* out on September 8th, and part two being with Mojang only knows what in it and it’ll be out when it’s out.
There, HAPPY NOW?
