Core Data vs. EOF

Hi all,

I see that a more detailed overview of Core Data has been posted on ADC 
<http://developer.apple.com/macosx/tiger/coredata.html>. It seems 
pretty similar to EOF, but without the flexibility of connecting to any 
SQL data source (they list XML, binary and SQLite).

  "Core Data builds on some of the concepts of enterprise-class database 
application frameworks, such as the Enterprise Objects Framework in 
WebObjects. However, make no mistake, Core Data is not an 
object-relational database access framework. Instead, it uses concepts 
from the database world to take application data management to a new 
level."

Is there a relationship to EOF? Can it replace EOF? What do you 
long-time WO developers think of this new framework on the Cocoa side? 
What are the implications (if any) for WO?
