i would much rather wait patiently for a release date than to see them set one now that is for months away..
Probably worse would be for LDW to set a date and then for some reason be unable to release the game then, thus disappointing thousands of people.
Remember the game is still being refined and tested. It is always possible that an important _bug_ may show up just before they are ready to release the game, and they have to rewrite the code to fix the _bug_, delaying the expected release.
