I think you're right on all counts--triples will probably be the ceiling, doing extra flips isn't necessarily harder than odd axis stuff, and there should be a way to score style beyond personal preference.
You've got the industry insider perspective--talk to the people who made Amped 2 and post up on what you find regarding their algorithms.
There are some other messy questions in here though.
Big name events like the X Games are content for broadcasting networks. They exist to make money, not to provide a venue to explore what's possible in the style realm. People watch them because they want to see people risking life and limb and triumphing. Judging standards reward the "hardest" trick not only because it's the current feeling in the ski world, but because that's what people who aren't skiers grasp. To the uninitiated watcher, style may not be something they can even understand, and there's no better proof of that than what happens when they do text voting (dub tens vs. superman double frontflips).
Furthermore, how do we go about changing the attitude within our sport? Do we hit a wall first, head for regulation, and then move in a different direction? The Olympic questions are only going to make this worse, because more energy, time, and attention is being devoted to FIS regulated events that qualify for the big show. FIS is doing a good job of listening to people like the AFP, but it's obvious that they're still getting the basics of judging skiing--trying to shift that to a style based system seems fraught with difficulty.
My personal belief is that the change we want to see will come(if it does) from within the sport--in the shape of non-traditional comp structures, things like the Orage Masters or the Back 9(remember that?). Whether we succeed or fail will be determined by the ability of skiing to muster all the money that's going to be thrown at it to develop these non-traditional comps rather than the big shows that see us as content, not as an end unto ourselves.
Not that I care that much, because skiing is about having fun, and as far as I'm concerned, nobody is the judge of who's having the most fun.
