Final Fantasy XIII demo came out in Japan with the Advent Children Blu-ray (Click Here for more on FXIII demo in Japan). It was suppoed to come out in June in US, but it looks the Advent Children Complete Blu-ray movie will be coming alone without the demo. Why? It is because Square Enix does not want Xbox 360 games to be left out since it would technically be an exclusive PS3 demo due to the Blu-ray content. Perhaps we will see FFXIII demo on XBL or PSN in US soon.
