Plasma is still revered and a lot of us who own them, have little interest in 4k. But when you start talking sizes such as this, a pull down screen and projector might be more up your alley. I've seen Epson's more modest model, the 8350, and thought it spectacular. If your budget is higher, I've heard nothing but good things of their high end models, which cap out I believe at $3500. Just factor ceiling mount and a screen, and a long HDMI cable(s).
So if you have a seating distance that allows something larger than 80", you can keep your great TV for regular use, and then close the shades and pop some corn!
Not to derail your thoughts, if a big TV is what you want, I think either would be a heckuva experience! They are new though, shop by manufacturer warranty info too!
