This from Frelorn today:

We are shooting for the end of April-ish for Update 16. We had scheduled it to be completed sooner, but thanks to the Snowpocalypse that was the month of February here, we pushed out the timeline a bit to ensure the team has enough time to get everything done they need to.

There may also be a smaller update before that as well, depending on a few things. More information will be passed along as we nail down the details.
