I can't even tell whether or not you're just being sarcastic, but that's the (estimated) release date for the full, and final (there'll still be updates though) version of MineCraft, which obviously isn't 1.8/1.9.
actually there is no release date
Yes there is. At least, an estimated release date. Jeb guessed that it'll probably come out on the 8th of September, as said on his twitter.
On-topic: Even though I prefer waiting for the update, this still seems like a good mod (and effort) despite the fact that not everything's in it.
Guys, you do realize that he has a life. A.K.A school. He still codes a bit there though, and he will be able to start coding again in about half an hour to an hour. Give him a break, he is planning on doing as much as he can before 1.8 comes out. To the people saying there is no point, I agree with one of the guys above. Knowing notch, the update will come out later than expected.
