I don't see Apple including NFC for anything. They have airplay and airdrop for sharing as a counter to NFC sharing, plus their passbook app very clearly was placed in as an alternative to NFC, simply because they went ahead and implemented the barcodes in the cards that needed no NFC capability to work at all. My guess is that they meant to put Passbook in there to pacify the no-NFC complainers.
In addition, not every country has embraced NFC payments yet, and those that do like the U.S aren't taking onto the new mode of payment in droves...
