Bitstreaming is coming though to nVidia Shield, probably with Kodi 17 Alpha.
Soon will be time to get an Nvidia Shield TV then
Same here, don't seems that we are going to get all bugs fixed like autoframe without wrapper.
I would suggest that by the time Shield gets 3D MVC and bitstreaming it will appear old and overpriced compared to newer hardware.
Himedia H8 firmware continues to progress and already has 3D, 7.1 Audio, auto frame rate (24/50/60) in Kodi without wrapper. It will continue to improve.
Himedia Q5/Q10 has incredible picture quality, I expect this will always be better than Shield. The HiSilicon chipset is simply better for video than the Tegra in Shield. The Kodi wrapper solution is not perfect, but it works and it delivers excellent 3D + 7.1 HD-Audio now. Not probably in six months. Q5/Q10 are also still being worked on and firmware will continue to improve.
A bit on a tangent, but next year (not before March) I expect Himedia to release a new Q5, using the same hardware but reduced spec / reduced cost (no LCD, no SATA, different casing etc). It will use the same firmware. This new product will guarantee continued Q5 firmware development well into 2016 and beyond.
