Total War : Shogun 2 - Fall of the Samurai announced.

[Intrepid Sidekick]

So, if you can answer this \/

Is this going to be like a whole new game where we are going to have to drop another $40-$60 (I can't remember how much NTW cost on its release), or is it going to be like RoTS where it was $15-$20 (Again I don't know its release price)

If you can't answer, no worries.

It is going to be a stand-alone expansion, if you own Shogun2 it will add to the original game as well, but you don't have to own "Total War: Shogun 2" to play it. And as far as i am aware it will be priced as an expansion. The price will be announced but I don't have the exact details.
There will be a patch at about the same time for owners of Shogun 2.

Hope that helps
