Honestly, I don't see this as a great play. Just like the 7 inch tablet rumors, Apple is risking arriving late to the party and having to work to get penetration, instead of being a frontrunner. I know, they have a huge user base, but that is eroding with the maturing of Android and the coming out of WP8. If they're not careful, they could lose users. For me, the iPhone has driven me into the Apple ecosystem more than anything else. If they lose iPhone customers, they lose the halo effect of the iPhone as well.
I currently have a iPhone 4S, but have been looking sideways at some Android/WP8 handsets for a little while now, for various reasons. One of them has been NFC functionality. I had the Nexus S 4G, and Google Wallet was very convenient to use, especially when it was combined with some of the loyalty cards as well. The marketplace may be a little slow to adopt, but technology is sound and proven. The possibility of a larger screen and NFC for the iPhone 5 has kept me in the iOS camp for my phone so far. Slipping on these issues may push me towards the HTC EVO, the GS III, or the next Nexus.
