Here's what I'm going to say about this: I'm still waiting for confirmation from our samsung rep regarding a question I asked her the other day. (I work as a tech at a corporate store).
What should be known: the "confirmation" that the epic 4g touch lacks NFC support is derived from the fact that there were no NFC related system processes running in the background when a couple of curious previewers decided to take a peek. As far as I know and from everything I've read, there still hasn't been a claim made, nor evidence of, that the Epic 4g touch is actually lacking the hardware for it.
So I asked her point blank and she didn't know the answer: is the phone actually lacking the hardware for NFC or is the software to run it simply not included (yet)? I'm waiting for a reply, so stay tuned. Also, by tomorrow, I'll definitely be taking one apart for practice, and I'll do a little microchip research to see what I can find on my own.
EDIT: also, read my words carefully. I said "as far as I know", meaning that there may have been a post somewhere that I never read that shows proof of lack-of-hardware, so if there is, I'm sorry, but please post it here
