Any time a given Drupal core development cycle is more than six months old, people start asking "When will Drupal X be released?" The answer, of course, is always "When it's ready. Please help us finish it." That's well and good, and I don't propose that we change that position. Volunteer labor and fixed release calendars do not mesh well.
However, knowing when Drupal will come out, at least in a vague sense, is increasingly important for core developers. The web is changing rapidly, even more rapidly than it has in the past, and knowing what the web will look like around when Drupal 8 is released is critical. Not only so that we can target the right features to get ahead of the curve, but so that we even know what our available tools are.
A few weeks ago, I and several others helped some friends of ours pack up their apartment into a truck in preparation for moving cross-country from Chicago to New York. It was, as such moments generally are, bitter sweet. It's always a good feeling to help out a friend, but when you're helping them get further away from you it's not as pleasant.
Of course, me being me, what struck me most about the whole process was how well it served as a model for software development and project management in general.
