Wow. I was all set to object but upon running a search, you're right! Out of over 20k populated, non-permit systems in the bubble, it looks like there's less than 300 left that would be eligible to place a new PMF (my search criteria being: no current PMF, six or fewer current factions, populated, no permit lock). I would guess the vast majority of those are in expansion range of an actively expanding PMF too. So, yeah, bubble's basically full.
Seven or fewer current factions has been the (undocumented) rule for several years now, so there's about 2000 left. But mostly not in places you'd want to start a faction. This was going to happen in a year or so regardless; the only surprise is that they're aware of the need to replace it with something else.
There are a lot of orphaned / abandoned PMFs that could (and arguably should, especially those with annoying names) be removed from the game, which would free up room.
It wouldn't free up very much, though.
1) It's really hard to tell if a PMF is abandoned or just not being supported very successfully / being beaten up by a bigger one right now. Any PMF in an even semi-busy system is going to get transactions supporting it every so often (especially if a bigger alive PMF strategically proxies it to stop new PMFs being added nearby)
2) Even if they go super-hardline and say that any PMF which doesn't control any systems is "abandoned" (which will get a whole bunch of false positives with accompanying complaint threads) it only frees up about 500 systems for new ones, because most of the space is being taken up by the 50+ system mega-factions, and that includes most of the systems with dead PMFs in.
Lads, you need to stop with the vague smoke and mirrors stuff. We as a playerbase fully accept that things happen, dates shift and all that.
The problem is that we
don't collectively accept that. This thread alone has plenty of evidence for that. There's huge numbers of complaints about the delays to the "major feature rework" - which could be anything and if they'd said instead that U14 would contain it we'd all have believed the Thargoid War was it [1] ... whereas if they'd just left that off the 2022 roadmap post entirely, they wouldn't have needed to mention it now and take all those complaints.
Fundamentally Frontier are incapable of making accurate statements about content or timescale of anything they do with Elite Dangerous more than 6 months ahead
at best. A succession of update posts like this one saying "yet again, our plans twelve months ago haven't worked out as expected; here's our new inaccurate plan for the next twelve" isn't going to help anyone.
Now sure, they could improve their project management to the point where they can accurately predict a 12-month window (getting to 6 months is fairly new for them) ... but until then, it's probably better if they just don't mention it at all until after it's released.
[1] Points for honesty for not pretending that whatever they
do change in U15 was it and saying that there'd be a second major feature rework in 2024, I guess? It was a vague enough initial statement that they could have done.
And there's
'Frankly we're not honestly sure that we're going to bother with it at all now but we don't want to say that because all hell will break loose, so we're kicking the can down the road for another nine months.' I mean this has got to be a record even by E D standards - it will be over 18 months between saying there's going to be an update to
something and even telling us what the something is
It was over two years between them announcing that work had started on Odyssey and them telling us
its name, never mind any of its intended features, so this just seems about normal for them.
