Is it asking too much to believe that Dark Souls 3 is not only in development but that From Software is ready for announcement at E3? Not only that, but that Hidetaka Miyazaki is directing it.
Hidetaka Miyazaki is the mastermind behind the Souls franchise
An unconfirmed source has informed VG247 exactly this. While it is very easy to believe that another Souls style game will come, it seems like wishful thinking that it could be announced so soon after Bloodborne and even more hopeful to believe that Miyazaki would return to direct after choosing to move on to Bloodborne rather than work directly on Dark Souls II.
If Dark Souls III is indeed a reality then it would likely be a multi-platform title and has probably been in development for some time already. Perhaps it is too good to be true, but we will know in two short weeks. Would you be prepared to die, again?
