I think 1yr is the sweet spot imo. And yes, not all the PS exclusives will be ported. I don't see Demon Souls being ported over for some reason. Only the big name titles.
But it's not just the big name titles, now is it? Sackboy is absolutely not a big name title, and that's getting ported, albeit two years after the initial release.
I'm gonna be honest...for my own personal use-case, I'm having to consider a few things here given the ramping up of Sony ports to PC. I don't suffer from FOMO, so I don't need to buy games Day 1, I can wait. I'm picking up GOW Ragnarok Day 1 but that's an exception...and it'll be the PS4 version anyway. Otherwise I've got no problem waiting months or even years to play games, I'm still clearing out Saturn and PS1 titles FFS!
Now I have to consider the longer-term. I've already resigned the idea of picking up a Series X; there is literally no reason for me to do so since all games are Day 1 on PC, then there's also PC GamePass I can take advantage of. Right now Sony isn't doing Day 1, but I get the feeling they eventually will for the live-service GaaS titles, especially any F2P ones. But if they start establishing a clear pattern where I can reliably know I "only" have to wait a year or maybe two for a 1P AAA release to end up on PC, with more features, better graphics settings and a cheaper price (if there's any online MP I don't have to pay on PC versus console), AND mod support on top of that, all on one singular device where I can do all of my other gaming too...
That's why I say, for my particular use-case, it's making me postpone a few upgrade plans. I'm seriously weighing the option to just build out a semi-powerful PC, get an eGPU for something I can swap between a desktop and my laptop, and just call it a day. Any Xbox 1P games I want, I can pick them up on Steam or take one of the many cheap routes to get PC GamePass and play that way. Any PlayStation 1P games I want, if they're Day 1 I can just pick them up on Steam; if not Day 1, I can guess with maybe 80% certainty they'll be on PC in 1-2 years and since I don't suffer from FOMO, I have the patience to wait especially if it's a single-player game (pretty good at avoiding spoilers).
I'm not going to say owning a console for my planned gaming habits/setup is going to be as redundant for PS as it is for Xbox, but I think Sony are treading a line where that could be the case very soon, and I'm just...surprised, is all. Maybe this PC push of theirs was on the fear they wouldn't be able to fix PS5 supply, but that problem looks like it's resolving itself, so I wonder if they will in fact pare back some of these plans WRT the ports. I have to imagine losing a customer who would've bought the game on a PS5 and given Sony 100% of the 1P sales revenue plus any number of 30% cuts from 3P software purchases on the console, to that person deciding to buy those games through Steam instead, isn't what they would ultimately prefer.
I still think Sony maybe should've tried a slightly different approach to PC. Instead of porting their marquee PS games, why not develop a new exclusive for the PC market? Something that would be a perfect fit for that market, give it some space and time to see if it takes off. You can maximize revenue for the usual marquee PS titles through the console anyway or by tying availability of those games through cloud streaming on non-PS devices like mobile and PC. You don't risk bleed of the console customer base in any way to PC, you still get your PC revenue through let's say an MMO live-service F2P game with those Sony 1P AAA production values that are extremely rare in the PC gaming space anyway, then if THAT game does solid enough, port it over to PS5.
Honestly I think that would've been the better approach to take when it comes to PC, oddly enough Sony had that strategy during the PS2 and PS3 days, I think it was worth considering again. All I know is the strategy they seem to be taking now, makes me consider if just swapping fully to PC is the best approach similar to what I plan to do with Xbox content. The funny thing is, I'm not actually begging Sony to support PC in such a manner whatsoever; if they had no plans for PC ports at all, I'd very gladly be picking up a PS5 this year, I've had opportunities to do so. I go where the games are, and that has usually always involved a PlayStation console.
But if those games, those 1P games, are coming more frequently and more quickly to PC, if there's a pattern forming giving me that sense, and if 3P games (particularly Japanese ones) are expanding to support PC more now than they ever have in the past....well, MS is also bringing all their games to PC, and if by some freak miracle of a chance Nintendo ever follows suit...well I go where the games are, where I can maximize my dollar as a customer and where I can have as minimalist a setup as possible, and that's looking like to be PC.
Eh, I'll see, anyway. Sentiments can change, I'm gonna see what feeling I can get for Sony's 1P release strategy going forward, what release strategy they have planned for 3P exclusives on the console side, and make some final decisions from there.
