I saw this in Himuro's LTTP thread, but I thought these books deserved a thread of their own. According to Amazon, they are releasing on September 30, 2008 and February 24, 2009 respectively.
Here's the product description of the first book from Amazon:
They seem to be full-fledged books, as they have 304 and 416 pages respectively.
Only one name strikes fear into the hearts of evildoers everywhere: Phoenix Wright, ace attorney. Join Phoenix Wright and his adorable assistant Maya–plus Miles Edgeworth, Detective Gumshoe, Franziska von Karma, and others–as they investigate twenty intriguing cases. And find out why Phoenix Wright has devoted his life to fighting injustice!
I can't fucking wait.
