Xaro Xhoan Daxos and Pyat Pree is a part of Daenerys storyline, which they has begun to change in a dramatic way. Daenerys chapters is slow, not happening so much in them, they can use to television. And they created Xaro and Pyat Pree to be the villains, as they actually is. They have to show she has changed, from the afraid girl in the start and now she's is more independent.

So they have clearly an idea with Daenerys storyline later without Xaro and Pyat Pree. Daenerys storyline is the storyline there is most diffrences from the book.
