This exactly. This rumor is underwhelming. Who cares if they partner with Nordstroms?!
If they partner with major cards, I see no reason to partner with retailers one at a time.
I guess we'll find out in a week.
You still don't get it...
Many stores want you to use their own credit cards. They make huge $ from these (obviously that's why they're in the credit card game). Apple has Visa, Mastercard and Amex signed on but if a store has their own credit card they prefer people charging items on that rather than the big 3. Stores like Nordstrom won't adopt tap-to-pay for the big 3 because they want users to pay using their own card. This is why Apple has to get the big retailers on board (the ones that have their own credit cards).
Apple will have an iWallet/passbook type of app so you can select any card you own (including Nordstrom if you have one) to pay for the merchandise.
Stores without their own credit cards will adopt tap-to-pay for the regular cards with no hesitation...it saves time/fumbling around looking for the right card to use.
Hope that clears things up.
