Sony prepping Heavenly Sword revival?

Rumors of a sequel to 2007's slasher, Heavenly Sword – from Ninja Theory and Sony, have been floating around… pretty much since it's release. However, nothing solid has cropped up to either prove or dis-prove this rumor. However, it does get a little more interesting, as an IMDB entry lists "Heavenly Sword" (due in 2012)
