One thing that kinda confuses me a little:

1) "New Primal fights will be introduced"

Means more than 1 will get put into the game ( different ones)

2) "Either Leviathan, Shiva or Ramuh will be in 2.2."

I'm not sure if this is in direct relation to #1, but it sounds like to me it's separate from the "New Primals we haven't seen before"

From how I'm reading it sounds like there's going to be 2 or more Primals being added in 2.2 not just 1.
