My Little Pony LIII: Stashing Ponythreads Around in Case of Ponymergency!

[Topaz]

Now this is interesting, it appears we could getting our hands on some sort of official handbook in April 2013.
If the handbook is just taking information purely from what we have seen in the show, 144 pages seems a tad long. Of course, I guess it could also have behind-the-scenes information on the show's production.

Here's the B&N page for anypony who wants to preorder.

You can find it on Amazon.com as well, but you don't get the online discount.
