I think a bigger indication would be if Walmart discontinued Walmart Pay. Considering that people think that it's just as popular (if not more) than Apple Pay, I don't see them doing that or enabling NFC any time soon.
I did forget about the eReceipts. Just not enough to keep us using it. We got back probably well over $1K from the Savings Catcher program. Gonna miss that...Though Walmart Pay isn’t bad; I still prefer Apple Pay. Walmart Pay does have other advantages though like eReceipts, and express returns.
