Edmond Dantès
Dantès the White
The desolation refers to Smaug's ruinous effect on the area surrounding the Lonely Mountain, not Smaug himself at least in Tolkien terms. And we'll see that effect throughout the film.You think a movie called The Desolation of Smaug will not have Smaug? The beginning of your third movie will be the end of the second movie.
But yes, with a little bit of shuffling Smaug could be in the second film in a physical sense.
Whatever the case, Smaug probably won't die the second fim.
