This version of Phantom Brave includes the bonus chapter and all of the tweaks from the Wii version plus five extra characters. Hero Prinny and Unlosing Ranger are some of the cameos Nippon Ichi added to the PSP version.
Phantom Brave: The Hermuda Triangle is slated for release this March on UMD and PlayStation Network. Europe is getting the game too, but in PAL territories its PSN only.
P.S. Remember our puzzlenouncement? "A Remade Lighter Hunt" is an anagram for "Hermuda Triangle." The remade part was a clue plus, of course, the picture. Like I said in the comments, it was supposed to be the easiest puzzlenouncement yet.
