I hardly researched it at all. I read no interviews with Jordan or Sanderson nor with anyone else. My only knowledge comes from the books themselves :P
Still, I think I did a pretty good job with it, all things considered :P
Well, I already know which theories turned out right and which wrong :P
I just finished the book last night. Had to settle for two and a half hours of sleep to get it, but it was semi-worth it :P
Check the thread in the General forum :P
The book stores in Israel made a mistake and started selling the books as soon as they arrived in stock. The mistake, I'm told, had since been corrected (thanx I persume mainly to my thread, which made said mistake into public knowledge), but a few of us Israelies managed to get our hands on a copy :P
Had it for over a week now.
I just finished it last night :P
