Matt recently said that Australia/Pacific announcements will be announced the week of April 9th. I check every day because I am wanting to book for Feb/Mar 2020. I hope they are released sooner like you say!
I have been researching and looking every day for the announcements for Ovation to return because I already know which cabin I am aiming for. If there is another ship that goes instead of Ovation I will have to do some quick research!
