I wouldn't be surprised if they kept all 9 factions, but distilled them (at least in the beginning) to their most basic elements.
Crab - Berserkers/Monster fighters
Crane - Honorable politicians
Dragon - Monks
Lion - "generic" samurai
Mantis - Pirates
Phoenix - Spellcasters
Scorpion - Evil Politicians (though more likely they would just make the Crane the "Politicians" faction and the Scorpion would be the "Ninjas" faction)
Spider - Evil things
Unicorn - Mongols
I think it's unlikely if they keep all the factions you're going to see the diversity of themes you would have seen under the old model, for better or worse. Doing this also makes them easier to 'sell' to people unfamiliar with the setting, ie new players or players of their other brands who aren't familiar with L5R, which FFG will most likely be devoting most of their attention to. I think if there is a thing like Dueling, it will not be a Crane thing, but a thing everybody can do, and maybe there is a Crane guy or two that can just do it really well.
