I'm on PC and at work so sadly I can't test anything but the patchnotes state that:
Mileena (Ethereal) - Reduced the recovery on Vanish Away & Vanish Towards. Also allows for combos to continue afterwards.
If I read this correct the Vanish (Ex-DD2) is still the same?
Even with the enhanced versions being great the already steep meter-dependency leaves the question if Ethereal is still unplayable. That said I'm now much more optimistic for this variation.
One thing thing that I noted about the Vanish was that if the opponent "hits" you while going to the Vanish it still counts as a block. Mileena doesn't take any chip damage if this happens. Grandmaster Chub-Zero's enchanted slide stopped on it's tracks when it connected the Vanishing Mileena and I was able to pull a full punish with 123 starter while SZ recovers from the slide.
I dunno what the frame things were before the patch (last time I touched Ethereal was when the game got released)
But the current frame data is:
