Pongo aquí la información que he puesto en otro foro un poco más desarrollada:
Sí, finalmente Soul Sacrifice es un juego de Kenji Inafune desarrollado por Marvelous.
Planning/Development: Keiji Inafune
Development: Marvelous AQL
Music: Yasunori Mitsuda, Wataru Hokoyama
El concepto es bastante curioso e interesante. Eres un esclavo de algún tipo de mago el cual, para atacar, te ha "brindado" la habilidad de sacrificar objetos o partes de tu propio cuerpo (brazos, manos, ojos, etc) para invocar las armas...
Leed la descripción:
First details on PlayStation Vita's Soul Sacrifice have surfaced from Weekly Famitsu and the usual source for early Weekly Famitsu info, Sinobi.
Via Twitter, Sinobi reports that former Capcom development head Keiji Inafune is indeed working on the project. He's joined by Yasunori Mitsuda and Wataru Hokoyama on music. Development is being handled by Marvelous AQL.
The "Sacrifice" part of the title refers to your magic. When you cast a magic, you'll need to make payment through objects. You can use things like stones and trees as payment. But for more powerful magic, you'll be able to sacrifice your body parts. For instance, you can sacrifice your finger(s) to call out a Gleipnir. Sacrifice your eye(s) and you'll call out a Gorgon.
A separate flying get source is reporting that Soul Sacrifice will be released this Winter and will support one to four players.
Famitsu's feature on Soul Sacrifice spans seven pages and includes story and monster details, so we should have an update later today, and certainly tomorrow when Sony will hold a press conference for the game.
Excalibur: You stick your hand down your throat, pull out your spinal cord, and use this as your sword.
Gleipnir: Chop off your five fingers and perform a punch with your extended bones.
Gorgon: Pull out your eyeballs, and use them to blast out magic beams
Gungnir: Your bones and nerves emerge from your body and attack
Why would you torture yourself to kill your foes? This is actually part of the background story. You play as a slave who serves a cruel sorcerer.
It appears that you may be fighting people like yourself. Screenshots show massive creatures who apparently used their powerful magic too much and lost their human form.
There are still a few unclear areas about Soul Sacrifice -- for instance, if you chop your fingers off, do they come back? -- but we'll hopefully get additional details later in the day or at tomorrow's unveiling press conference.
Famitsu lists Soul Sacrifice as 50% complete. The game is due for release this Winter.
