Yes, I believe that at least a few core J2EE patterns WILL make it into the next version of the exam. (We don't know for sure at this point, because it will be long time before we create the new objectives for the update of the exam for EJB 2.1).
And I'm sad that they didn't make it into the book
but we will have some up. I HIGHLY recommend that after our book you get a J2EE patterns book, because our chapter-that-didn't-make-it was only a highlight...
We'll have some things on the web site, though
