It could be an FNP and the checkering with logo looks like it matches up. The magazine well/magazine baseplate contour looks all right also but it is hard to say for sure from the angle of the pic shown and so little of the pistol visible.
It certainly looked eastern-bloc to me at first also, but I think the angle and shadows are making what appears to be vertical lines in the grips out of what is actually checkering. Also, the magazine well bottom/baseplate and back of the grip on the Tokarev are much straighter.
I think this is what was throwing me off. When I first looked at it, I thought that was the FN logo, but I couldn't find any FN with verticial grooves in the grip and I was stuck on that. Now that you have pointed this out and I go back and look... it does indeed appear that the FNP is a VERY good match!
The funny thing is, unless I am mistaken, the promo pics show Snake Eyes with an FNP as well! I think you have nailed it and we will just need one more photo to prove it.
