I'm setting back and enjoying the ride with my P70 that is $4000 less and has great black levels. No HDR but wait there is no HDR content to watch. OK I feel better.
The point is next year or the year after there will be TVs with 12bit panels that have Full HDR with Rec.2020.
I just wouldn't fall for the next big thing. That a company says it has but can not be used for years to come. And by that time there will be something better..
Yes if a new 2015 P series was released with HDR this year. I would buy it. And still keep my P70 and only have $4000 to $4500 into to 70in TVs.
My opinion but a wouldn't take back my P70 for a 65js9500 and pay $4000 more. When I have great black levels and color after I calibrated the set.
I'm not a Vizio fan boy. My set of choice that I've own over the year was high end Samsung and Sony sets and not to leave my RIP Sharp Elite out.
Truth be told there using good business practices to get use to want to upgrade every year at this time because things really aren't set in stone for things like HDR ect. But we, they need to keep sales up.
Think of this you can bring your friends over and say yeah this set can do HDR and friend say cool show me. Your reply will there's nothing out there yet but it will be cool when it comes. Then it comes and your great TV that was new two years ago can't fully support the new HDR. Food for thought.
In the end get what you will enjoy
