Couldn't they drop the HDMI ports if they came up with an adapter from HDMI to the HDbaseT port? I fitted my computer with a DVI video card. Then I ran an HDMI cable from my TV into an HDMI to DVI adapter and everything works great.
DVI and HDMI were electrically compatible, all you needed to do was use a passive converter to reassign pins. HDMI to-from HDbaseT would require an active converter, and it probably wouldn't be all that cheap to build. I'm sure if the interface takes off someone will build one, but it won't be included in the box of every HDbaseT device.
