Dood, Karate Kid is TOTALLY a coming of age film, even without Molly Ringwald, and is not really a martial arts movie at all. 
I hear what you're saying. I still think that *most* things will be possible with the new system, but especially as characters enter the heroic and paragon tiers, trying to tell a "karate kid" story will be hard, what with all the running up bamboo trees and jumping over small buildings in a single bound. It's certainly a system where a desire to run "grittier" games might make people happier with older versions. And, I haven't seen the final, full rules yet either, so it's mostly guesswork anyway.
