Interestingly some information regarding Bloodborne has leaked and it seems as if the spiritual successor to Dark Souls will contain a smaller number of weapons, something that lead producer Hidetaka Miyazaki recently confirmed.
"In terms of how many physical weapons there are, the amount is less than in a Souls game, yes!"
"In a way, the variety is still there, but it's absorbed down on a customisation level, rather than in the quantity of actual weapons, much more than in Souls."
