I think it means that he's cultivating the emotional ground work to play the role. That said, I'll bet he's apprehensive to commit to such a massive project without knowing exactly what he's getting into. How long does it take to listen to or read all the DT books? I think that's when we'll get our answer.

I figure he's trying to decide if he can be a villain in the next James Bond film and do this one, too.
Gunslinger 4 hrs running time ( 6 cassettes)
Drawing 12 hours ( 8 cassettes)
Wastelands 18 hrs (12 cassettes)
Wizards 27 hours (18 cassettes)
Song of S 14 hrs (12CD)
Wolves 26 hours (22 CD)
DT 29 hours (24CD)
Kind of a weird choice. He can act for sure, but the physicality is all wrong. I can't see it, but who knows?
Maybe if he doesnt read them all at once he would develop better. 1 book for per film so he doesnt know whats coming like the viewer wont.
Javier Bardem was great in No Country... but he is definitely not Roland. The guy can hardly speak English. I don't see this working very well. >.<
