It was reported earlier via scrawlfx that Arcana Heart 3 will be released on 05 April via PlayStation Network. Well, we now know it will be released on a later date, 19 April to be exact, according to Aksys Games. A week after release, Aksys will release additional costume colors and a custom theme as DLC.
You still have to get your wallet ready though. The 19th can come soon enough.
