It will. That was just an example.

I’ve found however that there are fewer modes available for 3D FP on some displays. We pick the best refresh rate advertised by the EDID. This of course can be overridden.

Didn't work for me. All I got is a blank screen after the FP mode HDMITX command. Is the patch that you have mentioned included in the October update?

1080p & 720p 24/23.976Hz framepacking 3D are mandatory for all HDMI 1.4a 3D displays.  

 
And all commercial 3D MVC movie content will be 1080p23.976 (and possibly 24.000) in reality won't it?

There is some HSBS 1080i50 and 1080i59.94 and some HTAB 720p59.94 content (TV broadcasts mainly) which could be re-sized and output as 1080p or 720p FP at 50/59.94Hz I guess - but that is a real edge case?
