According to the article Walmart is shutting down gun sales at 500 of its retail locations. They have the option under the law to transfer the 4473s to other Walmarts selling firearms instead of turning those records over to the ATF as what happens when a FFL holder shuts down. However, what Walmart is doing is voluntarily turning over those records to the ATF which can then be digitized and store away. I'm thankful to say I have never purchased a firearm from them and also stopped buying ammo when they began to require a driver's license to purchase ammunition.
