This came out around two weeks ago and I did not see a whole lot of discussion on it ... and I suppose that says a lot about why I think it's a good thing. Presumably there was discussion on the current L5R forums and groups but outside of that I saw one article on EN World and one on Bell of Lost Souls and that was about it. Since then - nothing. L5R doesn't seem to have much buzz at all right now but becoming a part of Fantasy Flight will surely change that. The card game will get a lot more attention, there will undoubtedly be a boardgame or six released in the next few years, and the RPG will get a complete redo, I presume.
Big factor, IMO: FFG's big hitters are licensed - Star Wars, Warhammer, Game of Thrones - all are licensed properties and it's hard to plan for the true long term with a heavy dependency on someone else's universes. With a somewhat known brand & setting - in gaming circles at least - completely owned in-house, FFG can really dig in and take it somewhere without fear of a license change a few years down the road.
For me personally I have a very limited relationship with L5R. I never got into the card game - there were so many when it came out in the initial rush after Magic exploded! I was temp[ted and came very close to picking up the miniatures game but that's one I managed to resist. I do own a copy of the RPG but I've never run or played it. There just is not enough interest in fantastic medieval Japan here to ignite a session, let alone sustain a campaign. I have always thought it was interesting though, and I thought the "roll and keep" system was pretty slick. The 3E D&D Oriental Adventures was a nice book, used the same setting and I thought that might be one way to lure my players in - sadly it was not.
So while I have no real personal stake in the game it is nice to see that it is getting a good home with one of the "good" gaming companies.
