I was very surprised to learn,
via Reddit, that SWTOR's 2.4 patch had been pushed to the live servers! 2.3 just came out, BioWare means business with this 8 week content cycle. Of course, when I tried top patch it said it needed to be repaired. A long while later, I was ready to get data-mining.
There is a load of data to go over, but one thing stood out at me: new entries for the Rakghoul Plague. It certainly looks like BioWare will be bringing this event back, but in an altered form. In fact, based on the data below, it looks like they are adding a PvP component to the event.
