[Update: We've added hot new screenshots to our gallery, fresh from Atlus.]
We figured this might be what Atlus was teasing a few days ago, and it feels so good to be right. Atlus just sent out an email to the Atlus Faithful confirming that their Persona 4 fighting game collaboration with Arc System Works will be coming west. Wisely, they're dropping the convoluted Japanese title Persona 4: The Ultimate in Mayonaka Arena and just calling it Persona 4 Arena, which is much more to the point.
The console port will feature new story and online modes, which I was hoping for after having fun with BlazBlue's surprisingly enjoyable story mode. And luckily, we won't have to wait long: Atlus plans to release Persona 4 Arena as soon as this summer. Until then, you'll have to make due with preordering.
