[Book and TV spoilers] Arya's different list

[Unthinkable]

So Arya's TV list of names is quite different than the book list:

TV list: Joffrey, Cersei, Lord Walder, Meryn, Tywin, Melisandre ("the red woman"), Berric, Thoros, Illyn, Gregor, Hound

Bold being names not in the book list, crossed out being known to have "died" at some point by ADWD. There are some names from the books not in the TV list, but they are all minor characters or not in the show.

Does this mean Walder, Melisandre and Thoros should be expected to die in future books? Thoros is minor enough that the show and books could diverge, but naming both Walder and Mel speaks ill to me of their book futures. Particularly Mel, this is the first indication I know of that she would die.
