Since you originally posted I kept looking at pictures and clips of "Quantum of Solace" and could not tell what HG he was holding.
Just saw a pic on CNN and it appears to be the blued PPK. IMO, if the director and franchise owners are trying to go back to the beginning of how Bond came about then they should be using the PPK or older. Guess we find out in a week or so.
I will be on of the first one in line to see the new movie.
