as far as not adding NFC, i will say that i think samsung could of got away with it if they did add it because the visa/samsung partnership that was announced a couple of days ago allow mobile carriers and banks to launch mobile payments via a app on there phones using visas network, this could include tickets/coupons etc so thats another reason why samsung might of not included it but if that had a API, like google has for the google wallet and isis also has it that lets NFC mobile payments and also coupons with one touch,
another thing is that now you could have One mobile payment app with your credit card plus coupons etc and now samsung wallet app...
anyway good move by samsung for launching there wallet app
