The Dark Souls 3 Prestige Edition is now LIVE to pre-order on Amazon.co.uk for PS4, XboxOne, and PC. The price currently listed is a whopping
£292.11 for all formats! No telling whether that will be brought down to something more reasonable (could be placeholder price), but with the rumoured rarity of this edition it's not unthinkable to assume that this is the actual price! I would suggest keeping a look-out on Namco-Bandai's social media feeds for more information regarding whether this is the actual price or not...
Release date given is the 12th of April 2016
