E-Capcom is now accepting orders for the fifth main Ace Attorney game, and has announced some extra editions as well. The Extended Edition nets you a 3DS carrying case; the Figurine Edition nets you a Phoenix figure; the Limited Edition gets you both.
Also, ordering any of them from e-Capcom gets you an alternate sleeve for the game, picked randomly from a set of 3 (unless you order the Limited Edition, in which case you'll get all three.) The Extended and Limited Editions also include stickers with SD versions of the characters on them.
EDIT: Official site updated with a bunch of info as well.
