It should be no surprise that I'm a big fan of the Star Wars RPG put out by Fantasy Flight Games. Recently they announced Genesys a 'Universal' RPG using the same system.
I'll let FFG say it best with the quoted article below, but basically it is the core system behind Star Wars but in a system designed to work with any setting. This means getting the benefit of the narrative dice system in a western fantasy based dungeon crawl, sci-fi space adventure, or wild west romp through the badlands.
I wouldn't be surprised if FFG releases future RPG products with 'Genesys Source Books' for the worlds (such as L5R) but that is purely conjecture on my part.
Anyhow, you can find the press release here and more information on Fantasy Flight's website.
