This new Shogun 2 Fall of the Samurai trailer shows all the new stuff

This new trailer / developer commentary shows you a great deal of the new content that is coming with the Shogun 2 stand-alone add-on Fall of the Samurai. Sea battles, the extended campaign map, steam railways and foreign veterans are shown off too. There seem to be quite some new content coming with this, which should justify the asking price of 30 bucks. You can pre-order the game on Steam and receive some pre-order bonus items.
