Sources confirmed the new iPhone 4G/HD will have video chatting included, and Engadget confirms it now too. They seem to have someone very close to the filming of the new commercials where a daughter and her mother are video chatting. There's not any official comment on the matter, but people talked a lot about it and I think it's pretty sure the new iPhone will have video chatting.

Confirmations will probably come on 7th June 2010, at the Anual Worldwide Developers Conference in San Francisco. There's still a question, though: will the video chatting be available over 3G or over Wi-Fi only, but Apple will probably talk about this fact too at the conference.
