It will be interesting to see if they embrace the 'THIS IS YOUR ROKUGAN' [a complete reboot, prolly with some sort of time jump], or they go the opposite way and retell the L5R story with different mechanics.
I for one really hope they take the first path because the previous iteration L5R was more like an MMO-RPG-CCG. It was set up great to allow the players to tell the stories they wanted told.
