Guess I will end up buying a C9 later this year. My hand was kind of forced with this too. The TV repair shop let me know today that my entire panel is malfunctioning on my B6, and that I would have to get it completely replaced. It would cost $1,100 just for that. Like I am going to spend that much to get a two and a half year old TV fixed, when I could just get a new C8 for barely more than that. My credit card actually also had an additonal year warranty on top of the default one from the manufacturer, but it does me no good, since it expired six months ago.
Next time I am going to spend just a little more to get a four year warranty. Ironically, the price I paid for a 55'' B6 in mid 2016 is the same as what I could have gotten a 65'' C8 for at the end of last year. I am expecting the 65'' C9s to cost close to $2700 at most at release, and a few hundred less as the year progresses.
Then again, who knows if the tariffs will in any way affect these TVs. They are from Korea, so hopefully not.
Funny enough, I had no retention or burn in issues with my OLED, and so it was certainly nowhere near as bad as the plasma was in that regard. Mine simply died. I still have a 42'' G10 that I use as well for 1080p games, and yep...it definitely has image retention issues. They eventually go away after months, but I also have permanent burn in from playing SFIV on it.
Tariffs only impact on China goods. Also if you are in the USA they assemble them in Mexico.
