I can understand that some details in a dial can be something we can't get used to, I have some too in other references.
For the holes, I'm totally ok with them (I must say I didn't like the 5970 very short hands used for LY and 24Hrs indications).
As for the Pt, yes, it is most likely that they'll choose a black dial as they already used the blue one in the WG version. I guess in a matte finish as the glossy one was already used in the 5271P (and is more dressy that way).
Interesting to read your feeling about the size as I had the same. I was wondering how the +1mm would look like on my wrist but it is perfect for such a complicated watch.
We'll see that and discuss about it when it comes 
Cheers, Mark
