GMT-MASTER ll "misprint" and new 3186 movement

[Scarface]

I am quoting Billy (TRF member name):

Baselworld 2008 Update on GMT-MASTER ll "misprint"

"...I confirmed at the Rolex both 4.4.08 with a Rolex rep. The truth of the matter is that the movemets of the watches with the dials that are missing the roman numerals actually contain the new GMT II movement (3186) as is found in the "ceramic" GMT II (reference 116710). Rolex put the new movements into the "old" (16710) to test the movement prior to putting it in the new case.... So the answer is that it is not a mistake, but an intentional variation so that Rolex could monitor more easily the new movement prior to releasing the 116710. They are obviously rare and limited. Sorry again for the bad information earlier..."

So the hypothesis is that all GMT-MASTER ll instead of Roman "II" actually contain the 3186 movement; thus, ll is not a misprint but, instead, a way to know that the new 3186 movement is inside the old case.
Carlos (Mandrake - TRF member) has confirmed a few days ago that his new Pepsi has the 3186 mechanism but he doesn't mention the dial print.

So, what do you think and most importantly what do you know?
