Jan 28th is correct for the French version. I almost ordered a French copy and, in my PMs back and forth with Rayxamber, I have a message from him dated on the 28th saying that he was ready to mail me a copy "tomorrow" if I sent paypal.
For the English version, March 13th is probably the best estimate we're going to get. I also preordered mine from GDG, but you got yours about a week before I did.
