Jeff;
Around 1990 or so I had this very scenario occur on a 767 during climbout over the Rockies one dark, overcast winter night. The captain's airspeed was the problem as the F/O's airspeed compared correctly with the Standby Airspeed. We flew the F/O's airspeed to destination and the Captain's airspeed slowly corrected as we descended into warmer air (relatively speaking - it was minus 15 or so), on final.
The same EICAS messages occurred to us as did on the Icelandic 757. We did not have to use pitch-power responses as my airspeed was unaffected. We wrote it up of course.
As industry experience shows, the problem, although extremely rare, isn't new, isn't isolated to the Airbus A330 and almost never leads to an accident if the causes and the procedures for dealing with the failure are understood. Going back to "old designs" is not the solution.
