Using an external microphone with iPad Air or the new iPad Mini I have an external USB microphone that works fine with the iPad 3 using the Camera Connection USB adapter and a USB hub for power. Can a similar setup be used for the new generation of iPads?

Edit: Just to be clear, an answer with practical experience or a link to someone who has verified this setup is preferred.
Theoretically, yes, it should still work fine. However, as I'm sure you're aware the iPad 3 does not have the Lightning connector. You will need to purchase a Lightning to USB Camera Adapter so that you can connect your USB device to the new iPads with Lightning connectors.
