No, everything will be announced at least 6 months prior to opening. They want people to have enough time to plan vacations.
My guess for announcements:
Announcement 1/2013 Announcement in November 2012
-Transformers
-FFL Replacement
-Springfiled
Announcement 2/2014 Announcement in November 2013
-Mount Crumpit
-New show in Toon Lagoon Theater
And then depending on construction timelines, the following could be announced in November of next year or in the summer of 2014.
-Wizarding World of Harry Potter 2.0
Announced in Summer 2014
-Universal Studios Orlando 25th Anniversary Celebration for 2015. Updated parade and a new show for Universal Cinematic Spectacular
-Redone KidZone
