Again, don't freak out people!
"While the Apple Dock Connector has lasted almost a decade without a significant design change, its one of the bulkiest components of an iPhone or iPad. That makes the Dock Connector a big bottleneck when it comes to slimming down future iPhones and iPads and giving them better battery life. After nine years, its in Apples vested interest to make a smaller, better Dock Connector."
"A full eight pins on the 30 Pin Dock Connector are dedicated to maintaining Firewire compatibility. The only problem is that Apple has abandoned Firewire in favor of USB 2, Thunderbolt and now USB 3. Its pretty much a dead technology. All of those pins can be reclaimed without impacting consumers or accessory makers (except in extremely marginal cases)."
"Thats not all. Weve also highlighted pins 8, 9 and 10, which seem to exist only to provide pretty marginal video-out functionality to a handful of iPods. Between both the Firewire pins and the legacy video-out pins, we can easily shave 11 pins off of a 30-Pin Apple Dock Connector, leaving just 19 pins total."
