These phones ship in just a week. NTT is rolling out FOMA. There W−CDMA 3G phone service next week. It's been in test trials since May. If you check out those phones the one on the right has a video camera in the hinge for video conferencing on your phone.
They're also planning on offering video on demand for these things. I suspect in Japan that will quickly mean scary business men watching porn on the trains but I suppose another use will be to watch movie trailers or sports highlights.
The prices start at $40 a month which is about the same as i−Mode phones but the per minute price is a little higher. 40 to 60 cents a minute. I think i−Mode goes down to 20 cents a minute on certain plans at certain times.
