Here's what's behind my comment regarding the irrelevance of color:
I strongly suspect that the new production diaphragms will come with transparent Mylar suspension. In that case, I would hope they turn out to have the mechanical properties of the white Mylar suspended diaphragms. This is nothing more than me reminding (reassuring) myself that, though less likely, it is in theory still possible.
I see, I did not get that it is what you meant and I did not catch that new production will come with clear surround. If it is the case then we need to abandon any believe in vintage clear diaphragms and in new clear diaphragms and just treat the new diaphragms as the new production, version 2011. The material it was made is kind or irrelevant as if it was Mylar 50 year back, Mylar 10 years back and now then Vitavox used anyhow different suppliers.  So, the production will come most likely with new diaphragms that very much might make S2 a different driver.

The most interesting question I would have is how new S2 drivers deal with those very idiosyncratic breakups that S2 has at very top. That amassing throaty texture that S2 has a very tricky – a bit more or less make deference between S2 sound rich as expensive as S2 sound like distorted.  I found that amp loading that drive S2 has to be set to much greater preseason then with any other drivers. If one use TAD for instants then 4 time change of loading did not impact sound as much as ½ loading against S2 driver. I use my own techniques to ideal the tube as much as I can (using very distorted tube) and to hold the very top of S2 with a very-very mild inductance. I am sure no one does it out there in the field but in my estimation it does the best with old S2 with white cone. Will the new S2 need all ot it> will it has that throaty texture? Will it breaks up atop? No one knows.

I am not planning to buy new S2 drivers. I have plenty vintage one but if it turn out that new production has a very substantial edge over new one then I might consider them. Still, I do not use S2 along but it works with my Injection Channel, so I think in way the difference between the old and new S2 in my playback will be less visible then in another playback.
