But the E3 2018 trailer does have it. And considering that the recent Days Gone trailers also didn't have the "Only on PlayStation" I'm just gonna ignore it and just assume it's Sony being inconsistent for no reason.
Then there was this "Only on Playstation" trailer from two months ago:
No Death Stranding. Yes, no Dreams either, but it's a niche title compared to those games in the trailer. DS should be there.
