Jeremy Horwitz of iLounge is reporting that a number of sources are stating that Apple will be the only one able to make adapters for the rumored new Dock Connector, arguably to ensure compatibility and control the ecosystem:
Responding to earlier reports that Apple hasn’t offered developers parts or specs for next-generation Dock Connector accessories, additional sources have confirmed to iLounge that Apple will be the exclusive initial vendor of a new Dock Connector Adapter, to be sold individually and/or in three-packs. According to sources, the Dock Connector Adapters will sell for approximately $10 each or three for $29, with Apple-branded new USB cables selling for $19 each. For reference, Apple’s MagSafe to MagSafe 2 Converter sells for $9.99, while international pricing for Apple’s earlier iPhone Micro USB Adapter is €9 ($11) or £8 ($13).
After seeing so many awful knockoff Dock Connector cables in the past, I think it’s fairly reasonable for Apple to sell cables initially. Although I’m curious how this would work with actual docks, I think Apple taking the lead in this transition makes sense.
