Being the major Potter-phile that I am, I can't resist but to put this out there: the next/last book's name has been officially announced.  Harry Potter and the _____ _____.  The name is actually embedded in a hidden easter egg on J. K. Rowling's website.  I must admit that I was sorely disappointed upon hearing the news of the new title and opening the article that the putz author included the name right in the first line of the article only to explain a few paragraphs down that, "oh, by the way, you can find out about the name on J. K. Rowling's site via a fun hangman game."

So as to not spoil the news (unless you already know), and to make it more entertaining, here are the instructions to the easter egg, as provided by the MSN article in question (spelling errors and all :), with a little more organization and clarity):

1. Open her home page.
2. Click on the eraser and you will be taken to a room - you'll see a window, a door, and a mirror.
3. In the mirror, you'll see a hallway.  Click on the farthest doorknob and look for the Christmas tree.
4. They [sic] click on the center of the door (ed: the center of the top panel) next to the mirrow and a reef [sic!] appears.
5. Then click on teh top of the mirror and you'll see a garland.
6. Look for a cobweb next to the door.  Click on it, and it will disappear.
7. Now, look at the chimes in the window.  Click on the second chime to the right.
8. Click it again, holding down the mouse button (rephrased).  The chime will turn into a key, which opens the door (drag it onto the lock on the door).
9. Click on the wrapped gift behind the door.
10. Then click on it again and figure out the title yourself by playing a game of hangman.

Gee, figure it out after I already told you the answer! grrrr.
