There's an interesting Kickstarter project built around expanding the new MacBook's one USB-C port. I think USB-C is going to be an interesting contrast to Thunderbolt in third party adoption. I'm really not going out on much of a limb here since it is "USB" but when you consider this port is non-proprietary and going to be on a lot of devises in the not to distant future, I doubt you'll need Kickstarter to find cables.
