According to this Siliconera report, SCEJ horror Siren: Blood Curse will be released on Blu-ray in Japan, as opposed to being put out in 12 different episodes via PSN, as it will be in the US and Europe.
As you can imagine, this isn’t the best news for horror-loving gamers outside Japan. The pricing hasn’t been set for the episodes yet, but there’s a rather strong possibility it’ll be more than the £29.43 (5,980 yen) it’s going to cost in the Far East. In one go. On a disc. Call is a wild hunch.
