Looks like May
Well this is interesting. GameWatcher has apparently found a $1 pre-order card at Target for Homefront: Revolution, which states that the game has a May 17, 2016 release date. Right now it's merely slated for a "Quarter 1/2" window, but this likely gives us a good idea of what to expect. Deep Silver did not comment on the discovery.
I'll give it a fair shake, but I don't think there's any AAA release I'm less excited for this year than this one.
