I once spoke to a Campagnolo USA rep about the non fluted cranks after getting one in the mail to drill and tap for a 74 mm bolt circle triple. Of course I wanted the classic fluted one. The rep told me that the newer lazer etched cranks when molded, had an electrical charge passed through the casting that alligned the molecules along the lines of the spider and as a result was actually stronger than the older milled cranks. If you check closely, the sharp edged stress riser at the base of the arm and spider is not a sharp edge on the lazer etched model either. I can't say that this information also relates the the engraved cranks.

That crank looks good on my not quite on topic road/path fixed gear, a keeper of the flame only in geometry.

Is there any truth to the story I have heard that the etched and/or the engraved versions of Campy crank arms broke due stress fractures from these processes?

What are the locations of the logos on engraved and etched crank arms?
