It looked like it resembles DMC, but I didn't hear specifically the game setup (RPG or not) resembles it.
An article from IGN:
As we reported in July Before Crisis: Final Fantasy VII and Final Fantasy VII: Advent Children won't be alone in Square Enix's attempt at taking gamers back to the world of the biggest Final Fantasy of them all, Final Fantasy VII. The latest issue of Japan's Jump Magazine contains first information on an action game starring FFVII vampire character Vincent Valentine. The game, Final Fantasy VII: Dirge of Cerberus.
In Dirge of Cerberus, players take control of Vincent, a former member of the Turks. The game takes place a year following Advent Children, which means it follows the events of the PlayStation Final Fantasy VII. The story begins as a mysterious group called "DG" suddenly begins attack of a peaceful town, leaving only one choice for Vincent -- to fight back!
Aside from these few bits, Square Enix has revealed nothing on Dirge of Cerberus. The few screens shown of the game all appear to be from cinema sequences, with one screen showing a line of dialogue where Vincent states "The meeting place with Reeve is..." Looking strictly at the game's artwork, one may think Square Enix has taken some influence from Capcom's Devil May Cry; Dirge of Cerberus should appropriately be a vampire game, making this a reasonable choice.
A Japanese release for Dirge of Cerberus is set for 2005. It's possible that this game will make it into Square Enix's Tokyo Game Show press conference, scheduled for 9/24. We'll be back with more at that time.
