When Sony has a deal, they are front and center with announcements and marketing like cod, destiny, Bloodborne, nioh, no mans sky, battlefront. Why didn't they hide the pc version of street fighter till closer to release? I mean there were far more attached to that game? Why didn't they stop hello games from promoting special editions of pc, release info or remove the steam page. This has more of a chance of being a square enix fuck up than Sony deal.
Hiding the pc version could result in more preorders for console version so square benefits from shipping as many copies of the game on day 1 as possible and benefit from day one positive reviews and copies being available in stores. Believe it or not, square isn't hugely behind pc as some of you want to believe and there is proof of it from their previous pc release strategies. For the time being, They just look at pc as an additional source of income instead of primary source. If it was the opposite, all of their games would be day 1 on pc.
