So far so very good for the new QD-OLED:

OK, this is not a review of a manufactured TV.
It's a prototype that the writer got access to at a Sony facility. This could be carefully-made prototypes which cost way more than panels which they hope to make at scale.
The question about this new type of OLED is what the yields are going to be like, which his going to affect how they price it and when it's available.
Some people on AVS speculate that they may ship in low quantities towards the end of the year.
The price premium over LG OLED may be 100% or more.
