Nope, the answer is lower prices AND BETTER FILM's and more spectacle, Who the hell cares about frame rates. No one will even notice they already experiance 4k 60 on a daily through youtube.
A family of 4 can cost upwards of £30-100 in some parts of the country. A 100quid!
The future is streaming and premier access. At those prices anyhow.
No hassle of parking, turn the TV on, popcorn in the microwave 20 quid job done family entertained for 2-3hr's,
In all honesty, i don't think the general going public couldn't even tell you if they where listening to stereo, 5.1 or full atmos and people go on about hi-res music.
The public want spectacle something they have never seen before high frame is not that.
What's special about cinema these days, there's just something there's a magic missing, i remember watching ID4 on opening night, people cueing to get it, people clapping and laughing when the aliens got what was coming. Everything these days is marvel, its boring, now there's another 10-year plan for those coming 10 jeffing years!
I remember spending the summer with a virgin movie pass watching, fight club, tazan, ganster number one and so on.
The bottom line is whether people like it or not the next big film spectacle will be avatar. Camaron is one of the only directors working today that still knows how to get bums in seats. The films have developed new techniques and will deliver a film experience no has ever seen before.
