Good news for PS3 owners. Looks like we'll be seeing a demo for Heavenly Sword soon, according to a blog post made by the game's producer Mat Hart, who posted, "Keep an eye out for this in the very near future...and i mean very near future!"
The game is currently expected to release in September and Mat estimates that they are 95% finished with the game. He warns, though, that that final 5% could take a while.
The blog post also discusses the history behind the game, the length of the game, some gameplay mechanics, and his Xbox Live gamertag (c4rp3r). Check out the full post here.
