The 4K Blu-Ray is very likely to use 10bit+ (though it might take somewhere between 1-3 years for it to become available, I would guess), but it might stick to 4:2:0.
Maybe some 4K Blu-Ray players will be able to dither 10bit+ down to 8bit. That would be a nice workaround for displays with 10.2GBit/s HDMI chips. HTPCs will be able to do that, at least. So if you're willing to use an HTPC, 8bit 4:2:0 isn't too much of a problem. Probably a Lumagen Radiance could do that, too, if it has 18GBit/s HDMI input chips. But even with 18GBit/s I fear that 4Kp60 might not be possible in 3D. But I'm not totally sure, haven't done the math.
Thanks a lot for your reply.
As you write there are many questions without clear answers, at least until BDA will release 4kblurays specs.
But when will it happen?
... The sony upgrade... mmmm
Maybe this could be the real difference between a 1000 upgraded and a 1100.
I don't think Sony will provide a further upgrade for 1000 but I could be wrong..
Very very strange situation...
