@sndwurks: D&D5E is actually Pathfinder's biggest competitor. What I mean is, Pathfinder took the lead as WotC rolled up D&D4E. But 5E has recaptured the territory. One of the key strategies for doing so was broadening 5E's appeal beyond the existing 3E/Pathfinder or 4E player bases. FFG needs to basically do the same with the L5R license more broadly.
Which I feel can be done better with thematic reboot than a "canon" reboot.
There is also the argument against the Star Wars EU analogy in specific, being that Disney is not returning to the timeline of Episode 4. They are advancing the timeline forward and moving to a thematic reboot as well. The continuity of L5R is not the continuity of Star Wars EU, after all. The continuity of L5R is the continuity of the Star Wars films.
