I can confirm this is true - it was announced in the Q&A after the speech and there was a short break in between the two, so some sites thought it was the end of the relevant information and just left:

In the post-keynote Q&A, Kutaragi was quizzed on the lack of the key HDMI standard in the lower-spec PS3, and he commented: "At the time of E3 there was no [consensus on] HDMI", and that Sony was"concerned that it was overkill." But reception from the press and manufacturers has caused the company to reconsider. He didn't quite confirm that all models of PlayStation 3 will definitely have HDMI, but slyly commented:
"If you just open the model on the day of the launch... you may see HDMI."
When asked about the expensive nature of the PS3, Kutaragi somewhat bizarrely claimed that in the U.S., the $499 pricing had retailers and manufacturers happy at "such a great function for that price", trying to paint a picture where Europe was similarly happy, and it was only Japan (where the lower-spec model is 59,800 yen, and the higher-spec price up to retailers) that price came up as an issue.
He commented: "We set the price in other currencies and converted back to Japan", but there has been a change of heart, and he directly stated that the lower-price model will now be below 50,000 yen in Japan when it launches - presumably 49,980 yen, an effective 10,000 yen price cut for the machine.
