I was not saying that we should know these pics "soon". I do not think we can saw these photos (if they really exist, anyway), at least not in the following few years.
As for the films and cameras that were confiscated I do not think the Bolsheviks would have distroyed them. They were not fool. These pics are documents, and precious ones. They must be in some Russian Archive. But I do not think we may see them soon. However, I suppose that the mug-shot style photos must have survived too, and in this case I think that they could be known in a relative near future, for they are not offensive, nor morbide ones. Just faces...
