I just for my copy of the Journal Today, and so far is seems pretty nice. As you can see it's made in the same style as the Elements of Harmony Guidebook. It's the same exact size as well, save for being shorter/thinner(it balances out because it has a lot of text in it, unlike the EoH book which was padded with a lot of pictures)

On a quick thumb-through, it has some interesting entries in the Celestia/Luna portion as well(which is the first 2/3 or so of the book, all the journal entries from S4 as printed as well, much the same way the EoH book at all the Friendship Letters in it)

You can get it for around $11+Shipping at Amazon right now:
