If I have to guess what I think it will happen is that not all games will be ported anymore.
They originally said that didn't plan to port all their games. More recently Yamauchi said they weren't working on a GT7 pc ports and that didn't have plans to port it there.
Games like Sackboy, R&C, etc that were not profitable won’t have sequels ported to PC anymore.
Not true, both ports must be profitable. We saw in the leaks these porting costs:
Sackboy is a shorter and smaller UE game developed by a studio who also works on making multiplatform games or porting, so pretty likely its PC port cost must have been even cheaper. But let's ignore and let's assume a worse case scenario where its port did cost around $2M too. $2M to be specific
We know Sackboy sold 62.9K units in its first 3 months as can we see in this graph from February 2023, so by now must be above this.
We know that during these first 3 months it only had a two -33% discounts:
So most of the time was sold at $59.99 and during these discounts at $39.99. Let's assume the worse case unrealistic scenario of 100% of these copies being sold at $39.99, removing the 30% Steam cut Sony got $27.993 from them. $27.993 x 62.9K = $1.76M revenue
In a more realistic scenario, where most game sales are made during the first weeks at full price, on average these 62.9K copies would have been sold at an average of $49.99, and Sony would have get $34.993 from them. $34.993 x 62.9K = $2.2M revenue
So in a worse case scenario where that port costed $2M, the Sackboy port was already profitable after its first 3 months. And obviously any future sale would mean more profit.
Rift Apart PC port is at over 200K units, so it's profitable too.
All PC ports are profitable. And we see in Sony's fiscal reports that their 1st party games generate hundreds of millions in revenue per year, with a huge YoY growth. It's an important and very profitable business for them with a very low risk because every port is very cheap and is always profitable, even for the games like Ratchet and Sackboy that sold very little in PS before.
With the cost of their games skyrocketing and their sales/price/revenue not increasing at the same pe, they need to increase their profitability margin, and PC ports give them more profitability margin at a very low cost/risk. So they obviously will continue increasing their investment on PC, not decreasing it.
