Doen anyone have any insight about this camera. Looks awesome! What features does the GH4 have that the G7 lacks? WHy would I spend double the money for a GH4?

1. 29 min 59 sec. clip length limit. Limits use as a locked down event camera.
2. No HDMI live out to an external recorder/monitor. HDMI is playback only.
3. Sensor is two years old vs. the newer GH4 sensor.
4. No DCI 4K @ 24 fps
5. 1080p60 is as high as it goes., GH4 has up to 1080p96 fps in FHD mode.
6. I'm not seeing a headphone jack.
