I don't believe they are actually available for sale just yet AND from what I have seen there are two issues..
1 - it weighs more than the Exos (well the mens version does)
2. No hip pockets !!
I debated on waiting for the new Exos before I bought mine and after seeing these "issues" decided to buy an outgoing model Exos at a bargain..
These issues however may not be of any concern to you as you are looking at a womens pack and there is no baseline weight (older version) to go off and you may have no need for hip pockets (I love hip pockets)..
I imagine we will see these new packs here in a few months..
If you don't mind the lack of side pockets, I would wait for the even lighter new Levity/Lumina from Osprey which is their brand new "ultralight" pack..
