Yes, Core Data is certainly one of the most important new technologies for developers in Tiger. This is really a dramatic addition to Cocoa, adding many new services like "declarative" and scalable object persistence and state management, and much more...

It is interesting to see how Cocoa, which was mainly perceived as a GUI framework, is quickly extending its reach to many other areas. From what I see, Apple is pushing for Core Data a lot toward us developers under NDA.
Public information about Core Data is scarce but I recommend this page at Cocoadev, which contains public information available about it.
