Apple's annual developer conference in San Francisco.
Logitech and ClamCase Teasing First Two 'MFi' Game Controllers
ClamCase has published a trailer for its GameCase iPhone controller, which connects via Bluetooth, includes its own battery, and supports all iOS 7-compatible iOS devices.
At the same time, Logitech is teasing its new hardware controller on its Facebook page. The position of the hands strongly suggests the leaked iPhone enclosure controller that surfaced from Logitech back in June.
Games designed specifically for iOS 7 will be able to tie into Apple's Game Controller framework, allowing for seamless connectivity to authorized third-party MFi devices.
