Welcome to the forum and thanks for posting your question about the CE of Diablo III. Typically with CEs, the copies we get are reserved for preorders. However, if there are any extra, they would be available for sale off the shelf on release day.
Sometimes, more CE are shipped to stores a little after the game releases so you might have a chance to get one, even if you don't preorder.
I hope that helps answer your question and let me know if you have any more questions!
