ZF2 will at some areas offer integration with Doctrine2. There are however no plans to ship Doctrine2 with ZF itself. Even if we would want to ship Doctrine2, it would be impossible because of contradicting licenses.
When talking about integration, you can think of:
- A ResourcePlugin for Zend\Application that bootstraps Doctrine
- An adapter for Zend\Auth that relies on Doctrine
- A Zend\Navigation adapter for Zend\Auth that uses Doctrine.
