I mean, you're going to see fewer articles/sigs on a week by week basis, yes. You'll also see more members, which I think you've already seen at this point. The entire goal of the Affiliate welfare system is that it's enabling our shared member bases to be active participants in all of these leagues. You're always going to have activity on each league, though, as people will have the ability to talk about whichever league they're invested in at the moment, or if there's a doubles week.
If you want to give priority to people who do their work here, you can probably expect to lose the Affiliate PT agreement from the other two leagues, but that's just a guess.
