I'm not expecting FF7R to go EGS exclusive. Square Enix won't want to generate negativity around their game. At worst, it'll be on all platforms and keys you buy on GMG/Humble and such will unlock on EGS. I doubt they will go EGS exclusive because it's an own-goal they'd rather avoid - especially when they are dealing with a core passionate audience on PC who are happy to drop a game for the tiniest of things, because the alternative selection available is incredible. And let's be honest - most fans who want a FF7 remake will buy it on PS4 (I am). Holdouts for PC will want it on their terms, or not at all.
You could say the same for Death Stranding, but it's still a tricky one. Kojima is definitely in that circle, cavorting with the likes of Keighley who seemed to be on a mission for EGS to succeed at the last TGAs. It's very likely he's been introduced to the right people, and their choice of publisher is concerning. But then Kojima also likes his projects to be one of prestige, and Steam is the big platform on PC.
Plus Death Stranding - unless it turns out to be shit - is a guaranteed seller. Control is by Remedy, who have a reputation for making games that don't sell (probably because they get tied up in exclusivity bullshit all the time). Lo and behold, Control also sold badly as far as I'm aware. The studio just has no audience because they never fostered one after the success of Max Payne, choosing instead to sign exclusivity deals with publishers who didn't know what to do with their games. In terms of risk, 505 were funding development of Control and Epic offered them a significant return on that investment, to the point where they possibly broke even before the game even shipped.
Death Stranding is different because 505 are, at best, funding the PC port. Turning a profit isn't going to be as significantly difficult as Control, so they may not be as inclined to minimise risk, and just take the sales on Steam.
We should also remember that 505 released Indivisible and Bloodstained on Steam - both games were EGS Kickstarter bait (highly anticipated, successful Kickstarter - good to generate headlines) and neither of them went, so 505 at least have some scruples about what they do and don't sell off.
On the other hand, Sony-published first party games currently have form for going to EGS, so this could be a SIE thing to fuck with Steam, because Valve and PC gaming are clearly a threat to PlayStation hardware or they wouldn't have made PS4 Pro (players switching to PC mid-gen is actually cited as a primary reason for making it).
