It's exceedingly important to note the difference between
frames per second and
refresh rate. NTSC (the standard digital video cameras use in North America and some others) has been 60 'frames' since its inception, but they actually don't display a full image 60 times per second. Interlacing is still the most common method of displaying and capturing images, which means half the image's information (pixels) are displayed in one refresh cycle, and the other half is displayed in the next refresh cycle. NTSC does this at 60hz to achieve an approximate
frame rate of 30fps. PAL (the European standard) uses 50hz (25fps).
Factor in SMPTE and the numbers get even more specific, and weird. (23.97 for 24fps & 29.97 for 30fps) There are some higher-end consumer video cameras capable of recording 'true' progressive frames, which must be translated and converted to meet other standards anyway.
ONLY celluloid film is capable of capturing full frames at the 24fps standard, without being translated. This is actually an advantage - you can 'overcrank' a film camera to record 60 fps, producing great detail without combing, noise, or abberation caused by the various digital processes in consumer digital cameras. Playing this 60fps footage back at 24fps gives the effect of 'slow motion', which has been around since roughly the turn of the century - more than a hundred years ago! Cinema-grade digital cameras, like the RED, offer similar versatility to celluloid - but it's still not quite the same.
Those in the know call it 'shallow focus' - a shallow depth of field. Consumer video cameras have wide DoF because they expect you to be capturing candid moments - your kid's sports event, or grandma's 90th birthday. The last thing a camera manufacturer wants is a layman complaining that the background goes out of focus, so they slap a zoom lens with a wide DoF on to sell more units.
More recently, DSLRs like the Canon 7D have been bringing shallower focus to the consumer video market. There's still a catch - if you just go out and grab a DSLR off the shelf, it comes with a zoom lens. This is great for snapping pics of various types, and even for general video use. What you really want is a 'prime' lens - a lens that doesn't zoom, so you can control the DoF.
This control over depth of field is the single greatest reason why cinema quality cameras look the way they do, and cost a fortune. Do not expect any kind of 'home cinema' revolution anytime soon. A good lens is almost always more expensive than the camera it's attached to.
After that, it's all about color. I won't go into detail at this time, but let's just say that digital hasn't caught up to film yet - by a lot. Feel free to PM me about cinema technique.
Do Not Be Fooled. This is a gimmick, and an even worse one than 3D.
What James Cameron is proposing is an upgrade to movie theater projection standards, NOT cinema filming standards. In an industry already competing with the direct download market, and the fact that DVD / Blu-Ray releases are rarely more than 6 months after the initial premiere in theaters, you can safely bet that 'a theater near you' will quickly disappear if this new proposed standard becomes commonplace.
TL;DR?
There's about a hundred factors that determine the visual quality of a movie, and frame rate is one of the least important. Increasing the standard will probably look good for action movies, but everything else will actually look worse.

Say what you want about his movies sucking, but a bad movie can't ruin cinema.
A bad movie that causes theaters to go out of business actually
can ruin cinema, by deterring customers who don't want to pay $20 for a ticket when they can just spend that same $20 after waiting for it to come to the home market (DVD/Blu-Ray/Download).
