The website was just translated:

"The troubles of Eclipse, are not over yet—-

The 12 Golden Keys that wouldn’t respond to the summon one day.

It was not just their appearance and personality that had changed, they even cut the bonds with their contractor celestial mage!

The sole desire of these rebelling spirits is, “Complete freedom”!!

Standing in the way of Natsu and Lucy, who are trying to restore the lost bonds, are the new twelve celestial spirits!

New Fairy Tail filler arc!"

Hopefully this is accurate, but now I'm even more irked because this seems to hint that these aren't alternate CS Spirits or "dark forms" rather the Spirits themselves. Yay for having to organise this on their pages if heaps of stuff goes down :/
