DrupalCons are a great way to learn and connect, but they are especially great to meet various people leading Drupal's future direction. DrupalCon Europe in a couple weeks is no exception.
There is of course the Driesnote to get an update on where Drupal's progress is and get inspired about where its going. There is a dedicated question and answer session with project lead Dries Buytaert where you can inquire about topics not covered in the keynote.
The initiative leads provide a glimpse into their respective areas in the Drupal Initiative leaders keynote. This is a great way to get to know the leaders and learn more about their plans and where you could help.
Various initiatives have dedicated sessions as well.
