This is what I mean about negativity. Everyone wants the Dev to release the next update as soon as possible, and quite a few of them are saying so every week. Devs have to respond to that, and try to give players hope that they wont have to wait too long before more content is released. So they try to put positive spins on release dates, even if they probably believe deep down that it's going to take longer. That's because if everything goes smoothly, without any last minute issues, then they could release earlier. Unfortunately, a lot of the time, there are last minute issues, and updates get delayed beyond the Devs best guesses.
So yeah, likelier than not, it will get delayed beyond those best guesses. But until that actually happens, why do you have to be so negative?
