Pretty likely yes. The next SSM announcement is going to be apparently something smaller than a big ass new game, so probably they are updating the original GoW games to keep them fresh for the PC audience and also having them modernized for the new people that may also come from upcoming movie / tv show adaptations.
This would be a bad announcement then, IMHO. At least as something to do as a major announcement at the VGAs. Something like a GOW Trilogy announcement could be better served as part of a SOP or Showcase, or a video announcement on their Youtube channel.
Beyond that if it's a console/PC multiplat release then they need to balance it out with another announcement that's focused exclusively on their console, particularly if "PC" here just means Steam. SIE have to get in the act of showing the console's still paramount in their ecosystem and that also includes balancing out new game announcements to where no matter what they bring to PC, the console's still either getting those games earlier, or a new game is releasing exclusively on the console around the same time (or not far behind it). I already went into that strategy extensively in
this post, if you're interested.
Parts of that post may not work anymore and I'd also concede that in the case SIE do a PC launcher soon, they won't make 1P games exclusive to it that have already seen quite successful releases on other launchers like Steam. So the Horizons, God of Wars, Spidermans, Ghosts ofs, Destinys etc. (and if they acquire Kadokawa, Elden Rings) will still see releases on Steam either simultaneously to a PS launcher or within a couple years or so after the console versions (assuming the PS launcher gets those games Day 1). But the general idea I had in that post still stands, and I still feel it's a very viable multiplatform strategy for them if they want to actually engage in a multiplatform strategy.
However, considering the optics they already have with their strategy, having ported so many games (I'm focused on non-GAAS here) to Steam the past four years, those optics do hurt the console some. You don't need to do a business analysis to see that, because at this stage a lot of that impact would be more in general enthusiasm around long-term outlook for the console within communities online & offline, even if these groups only represent a small portion of the customer base. And any lowered enthusiasm could have a range of financial impact on revenue & profits; a much, MUCH more intensive example of this is with Xbox consoles this generation.
So why flirt with that possibility, when you don't have to?
And well, also to make some extra cash before they release their upcoming new IP and new mainline GoW game.
At the end of the day most all of such remasters of old games are to drum up short-term revenue & profits, but there can still be a way of doing that with class and building towards longer-term value (financial & otherwise) for the IP and platform brand as a whole, without risking diminishing enthusiasm from a core subset of the audience.
If they want to do a GOW Trilogy collection for console & Steam, fine. But at least (finally) show SSM's new space game, or even in this case something as small as affording console owners a cheaper way to access those games & any QOL features vs. the Steam version would at least be
showing priority and rewarding their most loyal customers within the ecosystem.
The only game worth something there is Demon's Souls, everything else is a lazy cashgrab. The original God of War trilogy needs a full remake and it's not gonna happen.
Demon's Souls doesn't need an announcement there unless it's to announce a PS PC launcher. Bringing that to Steam, when (if they acquire Kadokawa) they are very likely to keep Elden Ring there and Bandai-Namco already bring Dark Souls titles there, would be a mistake and further weaken the market potential of their own launcher if that's something they actually want to do (or in addition, can further weaken enthusiasm among a subset of core enthusiasts which could have a range of severity in negative impact unto some areas of software & services revenue, peripheral or hardware revenue, and future hardware adoption rates).
If Sony kept Demon's Souls exclusive to their own launcher, realistically there's nothing people could bitch about. That IP's been exclusive to PlayStation systems since 2009 and while a PC port would technically break that trend, being exclusive to their own launcher still keeps it ecosystem-exclusive. And if any From PC fans want to complain about that, maybe give them a briefing on business and how, yes, even Steam still
VERY much relies on (defacto) exclusivity to retain & grow its market share in PC gaming (similar to the PS2 during its time).
So expecting other launchers to not leverage content exclusivity in some form to offer competition (not saying that's the only thing they'd need; high-quality features is also a necessity) is brainlet-tier.
