My understanding is in the CMA's view, CoD is such a unique beast, that they can't look at something like Starfield and say they'll do the same thing with CoD. Likewise they can't look at Minecraft and say they'll do that with CoD. It's such a juggernaut and holds such a unique position as a franchise in the games industry that they can't look at past behavior and say CoD fits a similar mold to what they did with this or that game.
They're arguing certain things could cripple their business, that I'm sure they themselves would like to do with future acquisitions. Maybe that strictens future acquisition remedies for Sony, but I don't know. Really everything Sony argues would hurt them immeasurably has already happened to a degree without foreclosing them.
Many 3rd party PS3 games were abysmal compared to 360's. Yet, Playstation is still around. Which really only goes to show how weak Sony's arguments against this acquisition are.
Without the actual numbers behind it, it's hard to see where the differences in the CMA's revised findings and Sony's model are.
I believe the CMA did use a higher LTV than the average customer using the justification that "switchers" are more hardcore and spend more.
Now, maybe Sony's numbers are right, but would they make a material difference in the CMA's findings? I'm not sure. Currently the CMA's findings conclude that Microsoft would lose billions if they made CoD exclusive.
Really depending on the percentage of "switchers" is what determines the profitability of such a decision. If 33% of CoD players on Playstation switched over to Xbox and ALL of those players paid 3x more in the Xbox ecosystem than they spent on CoD in Playstation, then Xbox breaks even from making CoD exclusive.
Any % of switchers lower than that and Microsoft would be losing money by making CoD exclusive. There is probably a margin of loss that the CMA would deem immaterial for Microsoft. But when you get to the actual percentage of users switching (probably closer to %15, but even at Sony's proposed 24%), Microsoft is still losing multiple hundreds of millions from a CoD exclusive strategy.
I'm not sure if the CMA used Sony's "3x the average" if it would even make a difference in their findings. But if they did use Sony's numbers, and it did change the CMA's findings, I'm sure Microsoft would argue against it.
