All those rumors on iPhone having an NFC chip inside turned out to be incorrect after yesterdays WWDC10 event. It seems there are also no plans in the near future.
NFC community was waiting this announcement in great excitement, since it would definitely boom the NFC era, but unfortunately it seems we will go only for Android in the near future. There has been news around the NFC APIs in the Android environment that they are stable now, depending on the hardware of course.
While Micro SD card based solutions are already out there awaiting for commercialization, I think that next big step now should be the availability of NFC chips and antennas in the upcoming Android devices.
