Current status: finished!
Want to help out? We're looking for volunteers to help close issues, and will be looking for QA help. We have dev sites available to work with real configuration and data from Drupal.org.
Tasks, which are not part of the initial D7 launch, but our top-priority post-launch are tagged with Drupal.org 7.1
For the details of the first phase of the project see Drupal.org Drupal 7 upgrade - Phase 1
