Update speculation thread: on a friday?

So yeah, Keen teased all of us pretty hard in their last dev note:

Since the anticipation for planets is very high and many of you want to know about the current status, we would like to share some info so we will not keep you in the dark. Planets are still under development and they are the number one priority in the game’s development. After the first internal iteration and testing, and since the last time that we shared some info about them, our team came up with some fresh and great ideas that will make this feature even better! So we made the hard decision to prolong the development a bit more but for a good reason. We are planning to share more detailed info very soon, so stay tuned!

What could be such a cool fresh new feature that it would be a good idea to delay the release of one of the most demanded and one of the most complicated features of the whole game to date?

I'm at a loss thinking about what could it be, any ideas?
