Well I'm glad that you're hyped for Bloodborne, but i highly recommend that you dont base your decision off of one game. Although the primary reason i got ps4 was because of all the destiny exclusivity, it seems more games run on 1080p on ps4, and amazing exclusives are coming to it that i made a good choice. System wise, they're pretty equal, but i hate the update sizes for the xbox one, and it runs a bit "chunkier" guess i could call it. But seriously, dont get the ps4 just because of bloodborne, there are many other reasons to get it, but be sure that they are the reasons you're looking for.
