From this point forward I don't think there is any need to worry about that. UHD Blu Ray has been standardized and so has HDR. HDR is already in the newest OLEDs I don't see a purpose for removing that feature and HDMI 2 A seems like it's going to be standard for higher end TVs going forward (and lower end TVs later). Only question is who will be the first to reach Rec. 2020
It feels like the OLED Big Bang has just exploded this past year with LG and Panasonic. There is a ton of hype surrounding the Panny TV sans the price. The only thing left is for others to catch up. JDI has been rumored to be developing small to mid size OLED panels; I'm guessing smartphones, tablets, and laptop/PC monitors (Sony already has small professional OLED monitors for sale since who knows how long). Interestingly enough I think these will be the first RGB stripe sub pixels for small(er) OLED panels since Sammy has been using diamond since forever (ugh). The panel in PlayStationVR is said to be OLED and RGB so I think it has to be an in house panel which will probably make it's way to other small electronics.
Samsung, I think will enter the oled TV business by next year.
Hopefully they use their own panels instead of licensing LG panels so it could drive competition (JDI too; Panny and Sony should create their own big panels in the future). Once they do hopefully we will see a bigger selection of screen sizes like we do now, 32 - 80 ins etc and prices begin to drop at a faster rate.
As you can probably tell, I'm very excited for OLED to takeover.
