Star Wars: The Old Republic Upcoming Patches Content Leak

It seems like the good old "open the files to check whether there's cut/upcoming content" technique has yet again worked, as the folks at TORHead have managed to find evidence of the content that will be added to Star Wars: The Old Republic in the next four major patches:
Patch 1.2 - Prepare to return to Corellia to battle each other for control over the Black Hole, scout the Lost Island, and head to the planet of Denova to battle it out against both the Republic and Empire.

Patch 1.3 - Discover the Legacy of the HK series of Assassin Droids, discover the horrors hiding deep within Belsavis, obtain Czerka Technology and aid Gree Droids as the mighty black bisector.

Patch 1.4 - Battle with the Hutts on their homeworld of Varl and take the fight directly to them.

Patch 1.5 - Trek to the ancient secret capital of Rakata Prime, do battle with a rogue Imperial Warlord and face off against The Dread Masters.
Obviously by the time the content rolls out there may be significant alterations, but the links still contain potential spoilers, so read at your own risk.
