I see alot of people assume that there wont be anyway aside from FCoB to obtain Carbontwine other than from World of Darkness in 2.55.

Question has it been confirmed? Or is everyone going of of the progression of 2.3x contents?

If I am not mistaken the Sands were available via hunts from day one of 2.3. I dont know why we wouldnt have a method get carbontwines from 2.5 out of the gate.

Has there been any confirmation regarding this particular subject rather than assumptions?
