100% accurate.
I'd add that on the PTS atm there are many areas of the game decorated with 'Dread Seeds'. Basically reworked areas of Tat, Corellia, Taris, Hoth, Voss, Balmorra etc. The areas are made to look decripit and the standard NPCs there are renamed to 'Dread Seed XXXX'. One of the new world bosses can be found in one of these areas but the reason for all the other 'Dread Seed' locations is as yet unknown. Looks like there is some 2.0 content yet to hit PTS.
New Dread Seed World Boss on Corellia called Lucky. If you die while fighting it you get the title 'Unlucky'. The 'Lucky' title is given if you slay the bugger.
