While it seems like Sony has a rather large backlog of PS2 classics to be upscaled to the PS4; Sony has confirmed that the JRPG classic, Arc the Lad: Twilight of the Spirits, will be the next title to be released when the PSN Store update takes place later today.
Twilight of the Spirit is the fourth of six games in the Arc the Lad series and the first to be launched on PS2 back in 2003. The JRPG follows 2 different protagonists as they proceed to follow their respective goals in a world inhabited by Humans and humanoid monsters called Demios.
No pricing has been announced for the game at this time.
