I just bought this flap in grey in the HK airport this Tuesday. Can't wait to pick it up in town today.
The pink one in terrific but I personally prefer the grey colour. It's a soft lambskin flap and the chains are very pretty and unlike the reissues, they are lighter in weight.
HK airport and Wynn Macau Chanel still have the pink one, I believe. I saw them at both shops on Tuesday and last week respectively.
I don't think US has them at the moment since none of my US SAs has ever seen the bag.
