I sort of expected this to be the case—they redid the BK near me and I started going there more often, and noticed that their terminals had the placeholder cards in the EMV slots. I figured it was only a matter of time after Visa cracked down on MSD that they'd disable NFC, but I'd guess that once contact EMV is certified, they wouldn't not turn it back on.
McDonald's has it everywhere, Taco Bell is on the verge of turning it on everywhere (rumors say next month), just about every sub sandwich chain supports it, a handful of Arby's locations around me do, Chick-fil-A, KFC, and Hardees, so I'd guess that Burger King doesn't want to be the only one besides Wendy's that's avoiding it.
I don't carry a Visa, so I'm a tad grouchy that they're breaking things for all card networks (arguably the merchants should've updated earlier, and it's for the best in the long run), but I do think the "lack of demand" argument could come up for places that don't want to mess with certifications.
