New Sites vs Classic Sites
The stated intention is that the most used features from classic Sites will be incorporated gradually. While not ALL the features will be re-introduced, Google say they are constantly monitoring feedback and prioritizing heavily used and top requested features.
Google Sites specialist Steegle has published a feature by feature comparison table showing what functionality is currently available in New Sites - See http://www.steegle.com/google-sites/classic-comparison for this and a wealth of other information relating to New Sites

"In 2016, we launched an updated Google Sites (referred to in this email as "new Sites") designed to help you create websites without programming experience, optimize across mobile and desktop, and co-build with real-time collaboration. In 2017, we announced that we are replacing the previous Sites experience, referred to as "classic Sites" with our new Google Sites product. Since that announcement, we've invested in the new Sites experience by building top requested features.
