Atlus USA updated their front page with a picture of cards and the words “We'll show you our hand”. The official announcement is coming out on June 9th, but RayFoxSith sent over a tip (thanks!!) with evidence that the game is the PSP version of Yggdra Union: We'll Never Fight Alone. Take a close look at how the cards look in the banner image above and compare them with the cards shown on Sting’s official Yggdra Union page.
They look identical and an announcement wouldn't be out of the ordinary. Atlus has a tight relationship with Sting and completed a translation of Yggdra Union for the Game Boy Advance. We’ll have to wait a week until we find out if the clue was correctly cracked. Until then take a look at this animated movie from the updated PSP edition.
