But before they do, they've created a microsite, A1SupportGroup.com, for fans sure to mourn the loss come December 21.
Harking back to Burger King's Subservient Chicken, A1SupportGroup.com offers all the support you'll need to get through the less saucy times ahead - coping tips such as keeping an A1 glove compartment stash, pre-recorded messages of support by the famous voice of Whataburger, and even a place for fans to upload fond memories and sign the burger's going away card.
All this hoopla begs the question: Is it really going to be gone for good, or is this just a marketing ploy? Does something this successful really get shot down in its prime, or will it rise again in the way of the McDonald's McRib?

I suppose we'll just have to wait and see. If the A1 Thick & Hearty is really toast, there are 34 days and 102 meals left to say goodbye.
