I am pretty sure the Tomcat and Hornet will be out this year, and the Harrier sooner than later as well.
Since Heatblur team has split from Leatherneck Simulations the progress in the Tomcat is going well. I keep an eye on their Facebook page where they post minor updates. They are working on cockpit textures now, the flight model is done or almost done and avionics development is currently underway.
Regarding Hornet:
And a quote from ED Forums:
"DCS is a true "sandbox" simulation that is also designed to cover multiple time periods of interest such as WWII, Vietnam, Gulf War and others. As examples of products progressing to completion for DCS, "Normandy 1944" is in final phase of development and
"Persian Gulf" is close behind."
