If you can tell it's the same sculpt, then they do look the same (2 &3), (4,5,6) for you to recognise that they are the same 2 sculpts
Not really, no. I can take a picture of you in one lighting, and a picture of you in another. and still be able to tell that the two pictures are still you, even if you don't look the same in them.

We know that 4,5,&6 are the same sculpts, only because they were taken at the same show.
2&3, Look similar enough that I'd expect them to be the same as well.
I'm confidant that the first two, and the second 3 are two different sculpts.
What I'm not confidant about is that the sculpt from pictures 4,5,&6 looks as terrible as everyone is making it out to be.
given the choice, based SOLY on the pictures we've seen, I prefer the look of the sculpt in the first two.
However, as the bale pic shows, crappy photography washes out all the detail . so we don't REALLY know HOW the "new" sculpt actually looks.
Additionally, we don't know what head she's going to come with UNTIL she starts arriving in people's hands.
