Griffin StudioConnect Showcased @ CES 2013
You can certainly expect to see accessories with Lightning connectors flood the floor at CES 2013 and we have already seen our first device from Griffin the StudioConnect.
The Griffin StudioConnect is an iPad dock which supports both audio and MIDI inputs and outputs. This gives musicians and bands the ability to plug their instruments straight in to GarageBand.

The StudioConnect is expected to be released around spring 2013 with a price tag of $149.99.
