As some people know Osprey Publishing is bringing out rule books made by other people. With the quality of a real book company behind them, this makes these games more appealing to a bigger group of people. Most game companies can't organize books for the life of them.
Here is there 2013 release schedule as of now, I am sure it will change of something else is added to it.
Now if I only could see what the Ronin book is all about that would be good to know.
