I think you guys should use the Scotty method from Enterprise for calculating the time required to complete a vital project.
Estimate the maximum amount of time required.
Double the estimated time.
Inform all concerned that the project can not possibly be completed before that time, but promise to make your best effort to beat the odds.
Complete the project sooner than [according to estimates] it should have been possible to do so.
Humbly accept the praise and accolades for once again performing a miracle by getting a vital project completed ahead of time.
And look on the bright side. At least you don't have Klingons shooting at you while you are trying to work, but even if you did, I'm sure you guys would find a way to work around it.
Sorry, but I have to correct you here. I can't remember which Twitch livestream it was (or how many weeks ago), but Diet did say at one point that the patch would be released before summer, and then defined the exact date. (I could be wrong, but I vaguely remember Sarah Otter sitting next to him, and think it might have been during the server downtime or shortly afterwards.) At the time, I was very surprised that Diet gave an exact date. I interpreted it as a sign of confidence in being able to stick to the planned release schedule.
I've begun to become much less explicit as I tell players when the patch will arrive. I still DO say that it's supposed to launch before summer, with the date that Diet once quoted, but I no longer give the same definitive answer that I told about a month ago. (In other words, I'm no longer making promises about exactly when it will hit, as I once did, even as recently as last week. I think many of us (especially the more experienced players who were around for Starfall) are beginning to read the signs and are starting to prepare accordingly...)
