Our primary goal is to get Elements shipped as a 1.0 product - the focus is to create the best static website builder on the Mac. Version 1 will not include a CMS. However, we have some plans on being able to work with online data sources, not to mention we now have the beginnings of Elements Cloud that open up a lot of possibilities. So in the short term no CMS built-in, but longer term things are looking very interesting.
Don’t forget, Elements also has an open api/language, so anyone can build solutions for it… perhaps once it’s launched someone will create a CMS for Elements or a way to connect to existing CMS systems
