The "60th Anniversary Edition" will be available in October...

"Beautifully bound and slipcased and printed on superior-quality paper gilded in elegant gold, this edition features a full-color map suitable for framing, a full-color timeline of Narnian history bound inside the book, and backmatter exploring Narnia through the eyes of its creator. A ribbon marker will help readers keep their place. This is the perfect indulgence for collectors and avid fans."
Looks awesome! My only problem is that I bet they're in the wrong order. Since they're celebating the anniverary of LWW, I think it would make sense to change the order back, at least just for this release.
