Not sure what comments you'd like to hear, but in general:
- 1314 generally very good BUT have the wrong hands (white instead of polished steel)
Hopefully VSF will fix this after the 1394 release, but you can wait as long as you like.
- All discussion about pam1394 takes place in the corresponding thread. We don't know everything we need to know about this model, but it clearly has steel arms, which is probably correct. I say probably because this model is anasized by panerai, but so far, as I understand it, it is not for sale.
I don't think there is any doubt that this is an existing model, however, that they have changed in design from the moment of the promo photo to the actual release - no one knows.
In any case, 42mm and 44mm are different watches, and I would respond to the diameter.
Now you can take any, and you either get a known flaw in 1314, or the potential to get them on 1394, although I do not think that other than some engravings (100 or 300m) and the thickness of the case, there is nothing to worry about.
If you decide to wait it will be possible to see how the 42mm model matches the actual live gen watch and see if the hands change to 1314.
In any case, the choice is always yours.
