Classically, the zorin team do not release active project updates on the site. And the only time they post a blog, is to announce when their latest project has been finished. I know this seems quite unorthodox, but the Zorin team consists of only 2 people.
And that number has not changed since 2008 when it all started. So ya, while that would be nice and all, don't get your hopes up. When it comes to the Zorins, this is just their way.
