1- Yes the external clean HDMI feed is always ON as fast as you switch to live-view mode regardless you're pressing rec or not. If you'll get this camera or the 1DC for that purpose make sure you choose the 4K mode in the video resolution menu. It'll be an APS-H crop but a fantastic image,  Said to exceed the C100/300 HD image quality. while the output feed in HD FF is identical to the mediocre internal HD. A Ninja 2/blade/VA on top/side of this is a very good idea especially to get that HD as well as all the other missing features like peaking/zebras and starting shooting 4K when clients request in the future.

2- Battery life is about 25-30% longer than the 1DC (in video mode). @Andrew @EOSHD_Twitter or any 1DC owner can tell us how long does the existing one go?

Thank you @Ebrahim Saadawi. This gets me excited. I hope Canon will surprise us with 4K HDMI output. I shoot weddings which are long (on average 3.5 hrs footage/camera for wedding & reception). I need to have lots of cards to record 500Mbps when decide to move to 4K. Cost is one factor but carrying and changing all those cards is just hard while wedding is going on.

Two questions:

1. Do I HAVE to record 4K internally in order to get HD 4:2:2 to external recorder? I shoot weddings and very few clients are requesting 4K at this point so I will be shooting HD for at least a year. I would not be happy with HD 4:2:0 which is done internally. I am just trying to find out if it's possible to record HD externally without recording 4K internally.  

2. Any idea on battery life while recording HD and 4K?
