She has already announced a Harry Potter encyclopedia. So no all the "cannon " as you put it is not out.
Also I have long expected more from her world. It may be a prequel or she may focus on someone like Neville. But Harry's story is done, that is all she has said.
That aside I am also waiting on more Eragon, would like more Dark Materials, and am desperately awaiting more from George R.R. Martin. His Song of Ice and Fire series is one I recommend to everyone.
Final* Word on Game Delays:
The game will not be any better or include more content then planned. Any commnets that say so are just PR hogwash to make you feel better for having to wait.
Delays are due to lack of proper resources, skill, or adequate planning by the developer.
Do be thankful that they have enough respect for you to delay the game and maintain its intended level of quality.
