I think the question as to when to use 10bit can be reduced to "Before 
encoding!". It will take a while before 10bit or 12bit has finally arrived for 
the consumers. I wouldn't be surprised if the higher bit depth didn't find wide 
acceptance before manufacturers have finally arrived at 16bit. I don't see how 
consumers are going to buy new displays with every 2bit step. Marketing may try 
to sell it, but consumers will have a hard time telling a difference and only at 
16bit will manufacturers find the most common ground and can pour it into the 
consumer market (i.e. still image processing is at 16bit for a while now) and 
only then may we see 8bit getting pushed back. We will also likely have 1080p 
and UHD everywhere with frame rates of 60Hz and more before this happens. Just 
my $0.02 opinion.
