The question I think the OP is asking is are people going to buy both Bloodborne and DS2 remastered on PS4?
Not a huge follower of the series so I don't know, but by logic X1 should have this in favour. People don't have infinite income, why would you buy both DS2 and Bloodborne when they're releasing mere weeks apart, surely 90% of PS4 owners are picking up bloodborne which is more or less a successor versus a game they've already played.
