Somewhat validating the apparent Best Buy slip-up last week, Persona 4's Rise Kujikawa has been confirmed as a playable character in Persona 4 Arena Ultimax via Famitsu
That makes a total of five new characters, along with Junpei, Yukari, Sho and Persona Sho, and it's likely that Ken Amada from Persona 3 will be revealed shortly because he was a character mentioned in the Best Buy description and the character's Japanese voice actor hinted as much.
Edit:
Release details: August in Japan for over 6,000 yen.
Seeing how the Best Buy description was probably correct, the western release will be on September 16. Hopefully no region locking occurs.
Edit 2:
New details:
- Japanese release date = August 28, 2014
- Price = 6,980 yen
- New mode = "Golden Arena Mode", w/ RPG elements such as leveling up, learning skills and customization and Social Links. Will be implemented in arcades this Friday.
- Story of P4AU might tie into story of P4D.
- First-print copies will have additional scenario DLC
August 28 is mighty close to September 16...
