Genuinely shocked by some of the replies on here.
It's a FREE mod, the guys (and girls?) working on it have day jobs, and they've stated it's going to be amazing, so releasing something that doesn't meet the hype would be counter intuitive. Those spamming the thread screaming for a release date would surely be first to complain should 0.4 be released and it turn out to be full of bugs.
Just be patient, if it takes another few days, weeks or months, the wait should be worth it.
