^ @ Above two posts. People cared about the characters in The Wizard of Oz. But, that wasn't the only thing that made the movie great even till today. It was a film that was advanced for its time featuring Technicolor and cutting edge Hollywood SFX...
Anyways, most people (like the above posters) would describe the light saber (fights) in the OT as slow and heavy, while the prequels showed us lighter swords that could be used as a weld/anti-weld to tear down spaceship doors...
Anyways, I could see some kid dressed up like Cloud (FFVII) wielding a friggin huge light saber. They had a librarian dressed up in a Japanese kimono in the prequels, so some character, maybe even the central protagonist dressed up like a space marine Cloud wouldn't be far-fetched... And, the big light sabers would be used not only for combat, but to cut down small aircrafts b4 the baddies have a chance to escape...
Or maybe, it's the Commander of a small team of Jedi's that gets to wield the big sword while his "underlings" occupy the periphery (of the battle scene) with the classic ones doing acrobatics at the same time. It's not just a matter of prestige, b/c the Commander has more responsibility to oversee the successful completion of a mission, which is why he is bestowed the honor of using the "big one".
Anyways, knowing Hollywood, they must (will?) try something different in the new trilogy to engage the audience. It would be more interesting, refreshing, something new to see a battles with much bigger light sabers b/c if people just want to see the classic ones in action, they have Episodes I-VI for that...
