Apparently this is because they routinely stop writing them leading up a new release. God knows why. It must be hard to write a few lines pimping your upcoming saleable product. it's good press and marketing FD could learn a thing or two from the marketing blitzkrieg that is star citizen.
Given a choice betewen marketing content that doesn't exist and focusing on creating content over marketing, I think I know which one I'd consider the correct approach.
As for OP's 'sky is falling' post, one of the most hilariously overblown reactions I've seen for a while. FD did specifically say in a previous update that updates would not be regular after that one in the build-up to releasing 2.1.
I've never really understood this need for constant reassurance that some players have, possibly because I started gaming when the only communication you ever got from game developers was magazine interviews. Now you go a few weeks without a dev update and people start to suffer from separation anxiety or something.
Yes there are games where the dev teams update players far more regularly, equally there are many where they update them far less regularly. I'm sure we'd all like to have weekly or even daily updates about what is going on but there's a point at which you have to temper that with the need for them to be actually working on the game rather than reading and posting on the forum or drafting update posts. We still get a weeky newsletter, what exactly do people think would be reasonable, a personal phone call from Sandro each week?
