Confirmée par Kutaragi,

A question on why HDMI only is in the high level version of the PS3 only. Kutaragi explains that sony was worried that if they put the HDMI in the lower version, some would complain about having to pay for something they don´t want. However, HDMI penetration has come faster than expected. He then asks people if they want HDMI in all models. Everyone in the audience says yes. He then confirms that all models, including the 20 gig version, will have an HDMI port.
