I agree with @Hazard. I think it's best to wait for the console versions and then see what all comes with the Steam version. Especially if you bought any DLC, at least you know it transfers over.
I'm basically saying the same thing. PS4 and if you want to get them all I might get steam. I am getting Steam and PS4 so... if you preorder you'll get those Halloween outfits for steam. But if you already have seen them then... it's a big whoop lol
