I'm no Dalek expert, but to me, going strictly by the promo pics, the colour is off, and looks bronze rather than yellowy gold. The control boxes for the sucker and gun arms look to my eyes to be maybe 15 to 20% too close together (there should be roughly, or just a smidge under, three metal bars worth of length between them when looking at the mesh and bars wraparound directly above them, if memory serves) - in fact the whole Dalek looks slightly slim as a result. Also if I recall correctly the skirt shouldn't be dual toned except, arguably, along top, the grille mesh around the neck should have much smaller holes and look more gold than black at distance (although this might be a licensor driven style choice as pretty much all versions of the Gold Dalek released tend to get this wrong and go with the standard black mesh look), the rings around the eyestalk should be a lighter shade of blue, and the black hemispheres look a tad undersized, a bit shallow as to how much they protrude, and also look to have a slightly odd shape as to how they curve (though the latter may be a photography effect, would need to see more pics to be sure).
To be fair, the proto pic they showed alongside the Third Doctor looked more accurate colour wise, and also around the neck grille/mesh. But now that just adds to the confusion as to which is more accurate as to what we'll end up getting. That proto pic also showed an incorrect silver gun instead of gold.
Additionally the warrior Dalek should have a graphite coloured gun arm, not silver, if we're going with Pertwee Day of the Daleks accuracy.
My views above are by no means definitive, mind, I certainly don't rate myself a true Dalek expert, nor have I watched Day of the Daleks in a while, so I might be off on a point or two, but that was my initial takeaway looking at them, for whatever it's worth.
Hopefully they'll put up a video of these to better judge by, and mention any inaccuracies that they intend to address in production. Doing so might go a long way in helping sell these to finicky folk like me.
