Couple of things: 1) People keep saying that F2P pays for itself by the ads that are shown. I would argue that the ads merely pay the costs of running the F2P servers. Jagex has costs involved with leasing the servers, bandwidth, monitoring, patching....all of which are overhead. My hunch is that F2P is, at best, a break even proposition for Jagex. Most large scale data center servers cost at a minimum a few hundred dollars (US) to lease. Bandwidth costs increase that even more. 2) Any F2P update would be also a P2P update. The only requirements would be that the entire activity would have to be "completable" in the F2P world. So a quest, for example, couldn't go from Varrock to the Fremmy Isles but it could involve Lumbridge. Should F2P get more updates? I would suggest that perhaps the easiest, cheapest, fastest way to do this is to release quests that only involve F2P areas into the F2P worlds. Or if you wanted to add a skill (uhm, let's ability to make steel claws) that it be added a year after it's released to P2P. That way there are no additional costs (other then porting the code into the F2P system) and very little overhead.
