Expected in late August, Panasonic will be shipping HDMI 1.4 cables out to Japanese retailers.
While there isn't yet a need for the cables, early adopters can get their hands on them at the end of this summer. Prices vary by length from a 1 meter cable running about $42 to a 10 meter cable at over $200.
While certainly the new HDMI standard will bring features formerly unavailable, such as capabilities for 3D content, as well as 4k and 2k resolution support, it's unnecessary until such technologies hit the mainstream market. A few products this holiday season will accept the new cables, and surely we’ll see plenty at CES. There’s no word yet on plans to bring these.
