Add the Sony HMZ-T3W's to the list. They are a bit expensive but have an incredible FOV. They also have a Japanese version that is a lot cheaper except the menu's are not in English.

The products below might require hdmi to video converter:
PIRATE EYE http://www.payatechnology.com
SKYZONE http://www.fpvmodel.com/skyzone-sky02-v2-aio-3d-fpv-goggles_g857.html (no website of the brand)
BOSCAM http://www.boscam.cn
EPSON MOVERIO http://www.epson.com/cgi-bin/Store/jsp/Landing/moverio-bt-200-smart-glasses.do?ref=van_moverio_2014 (at the moment they are not compatible with Inspire, but there are rumors DJI & EPSON are working on it)
p.s Zeiss Cinemizer production ended in February 2015, so the only option to get it is from remaining stock. I heard also some Fatshark models, like Dominator, are in the same situation, it has to be double checked.
Hope this post will help you to find your favourite FPV solution, enjoy your birds !
