I have a Bank of America MasterCard that expired recently and they sent me a new card, but when you go to their information page about chip cards (
http://bankofamerica.com/chipcardfacts ) it seems pretty clear that it's actually chip and signature. They emphasize that if you get asked for a PIN, you should tell the merchant it only requires a signature.
I don't know enough about chip and PIN to say if it's possible, but I'm hoping that means they'll eventually move to adding a PIN too.
All that said -- my iPhone 5 is coming off contract in a few weeks now and I definitely plan on picking up an iPhone 6; I'm looking forward to seeing how well Pay works.
