However, that’s not the case and you can pre-load the Japanese version (Samurai Spirits) now. The standard edition is ¥6,280 for a limited period (regular price is ¥6,980) and will gobble up 9.3 GB of storage. A Deluxe Edition is also available for preload and costs ¥7,800 for a limited period (the regular price is ¥9,180).
