Lexicon Steve believes she did.

She spent years planning her plot. When she put Scabbers, and 'young
Sirius Black''s motorcycle in the first book, she already knew the
Marauders, Animagi, Secret Keeper, betrayal, curse that killed 12
Muggles, sent to Azkaban without trial plotline. When she had Cedric
want to replay the Quidditch match because winning due to Dementor
interference isn't *fair*, she already knew she was going to kill him
in the next volume. 

I don't doubt that she knew all the major plot gimmicks before she
sent the first book out to publishers.
