I don't know if everyone will agree and notice the significance of this event but for me this is a MAJOR milestone in PHP community evolution. Drupal 8 will integrate with Symfony2. THIS IS GREAT NEWS!
I always liked Drupal. It is amazing! Community is huge and provides thousands of modules to solve almost any web-related needs you may have. To make it really embarrassing for the enterprise-level CMS solutions, Drupal often beats them in terms of features and quality. I have seen enterprise-level CMSes and they were just a legacy JUNK! There is no question about it, Drupal is awesome! Symfony2 is the sweetest PHP framework there is. Great architecture, patterns, cleanness, consistency, interfaces, testability, dependency container - basically all you need.
