A friendly reminder from GameFAQs:

And finally, if you're a Harry Potter fan and don't want the final book spoiled, just get off of the Internet now. The leaks have begun in earnest, and you're going to see lots of spoilers all over the place between now and the 21st.

Truer words were never spoken. I may come on the web to check my e-mail here and there, but until I'm done with the book, bye bye Internet.

See you Saturday/Sunday :D
