Giving a release date now would leave Jagex with two possible outcomes when the project inevitably takes longer than they expect, which it already has. They would be forced to either:
- Not release the game on the stated date, and instead simply announce it's been delayed. - Release the unfinished build they currently have, which will be buggy, broken and incomplete.
A release date will only be given when they're sure they'll hit that target - so we'll be given one a couple of weeks to a month out at most, though they may let us know the game is "nearly here" a lot earlier than that.
