java7

What is the most official Java 7 feature list? I find very little useful information regarding this on the official JDK 7 site. Apart from that I can only find blogs with people summarizing "some" of the new features.

However, some of these blog entries are old and some of them claim that these features "may or may not" be included in Java 7.

Can anyone provide a list of features that will definitely be included in Java 7?
I would also very much like to know the estimated release date.
Will it be backwards compatible with my existing Java EE 6 stuff. That is, will I be able to switch seamlessly using EJBs, JPA2, Glassfish 3 and so on.

The feature I am mostly interested in is Closures, so I'll happily switch to Java 7 as soon as a stable release comes out.

Thanks!
