I'll try to address some the questions all of you have.
In the past, they open for booking at 8:00am EST. We don't expect this to change. If you call, don't be surprised to be in the phone "queue" for a very long time. Do TA's have an advantage? I wish, LOL. We dial in the same as everyone else.
If you've submitted a fax request (before they closed this option for advance booking), you should be given the opportunity to book your cruise before the general release. However, this all depends on availability. For example, if there are 3 requests for a category 1 for a sail date and you're the third one, they'll contact you only if the first or second guests decline booking. (There's no way of knowing this in advance.)
Another thing to be prepared for is a different deposit rate. They raised them for the Mediterranean and they might do the same for the new itineraries. Again, no way of knowing that now, but they should release that info prior to the 31st.
We'll keep the DIS updated as the information becomes available.
