Due to a snafu with my NDA, and then waiting on WOTC to make me a copy for my use (they had already sent them all out, after all!), I didn't get my copy of the revised rules until about 3 weeks ago. I'm not blaming anybody, WOTC was very helpful in getting the stuff to me once it became apparent my NDA had been lost in transit.
This delay has a cascading effect on the release of the Anthology as well. When these last two books come out, I have to give them time to sell through before printing the Anthology. It has effectively shelved any thoughts of the Anthology for now and for many months following their release.
A change in the favored class doesn't just impact the prestige classes. It impacts the whole flavor of the race, which leads to questions like, "Why is there such an emphasis on illusions in this book?" It requires a revision of concept for the book.
But, ultimately, I am happy to be able to go back into the book, even if it's practically from scratch. Working with Illusionist as the favored class I felt like I was covering a lot of the same material we had covered for Elves/Wizards. Changing the class to Bard gives me more creative freedom and a chance to present some truly new things.
