It seems that Dark Souls 3 is ready for an announcement at E3 in two weeks time according to a piece on VG247 citing a source.
According to said source Miyazaki is back at the helm after taking a supervisory role on Dark Souls 2 and a director role on the PS4 exclusive Bloodborne.
Dark Souls 2 still has people bickering over which is better (probably helped by the recent re-release under Scholar of the First Sin). So, with Miyazaki back at the helm, so it’ll be interesting to see what the team do with Miyazaki back at the helm.
Remember, this is a rumour, so take it with a pinch of salt.
