I received the same email. I switched mine to clear cable. I ordered transparent colored acrylic anyway, so its not a big thing for me. Wasn't worth a few week wait for the new black cables. I did have to search for a pic of one with a clear cable though. Mine is #12371 impressions rxd 12/11. I'm not too uptight about late delivery but would like to have it sooner than later.
I got the same email. Mine is #12057 impressions received 6th Dec. BF acrylic.
