Yes! Sessions will both cover beginners and advanced Drupalers.
The official Drupalcon is a chance to learn more about where modules are moving in the future, and to meet the people behind the modules you use. In contrast, our tracks tend to cater to newbies and professionals working with Drupal. Showcase sessions show off excellent sites built with Drupal, by explaining what they do and how the were built. There are plans to hold beginner and immediate level sessions while other tracks can focus on development.
