I think it's pretty annoying to make unrealistic and inaccurate announcements about the possible release more than a month before. You could also announce the end of February if any other release date seems unrealistic, so as not to let your community stand in obscurity.
Many people have been hyping for weeks, although every staff member is more or less aware that February 2019 means only the end of February. You wouldn't have had to announce a specific release date, but at least a realistic period as short as possible.
Again, it's just my point of view and I don't know tactical backgrounds. For me personally, it always seems disappointing, as it subconsciously feels like it's shifted every weekend.
Nonetheless, I thank you for your work and hope for a timely release by, as announced, the 28th of February.
