Nickel and Diming

I recently was in a game store while on holidays, and came across the new 6th edition Pendragon Core Rules, wrapped in plastic of course, so I couldn't look into them. But I had looked into Pendragon before and decided that maybe this would be finally the point where I actually would take the plunge.
Imagine my surprise when the really pretty Core Rules book contained no DM section whatsoever. It's all on really thick paper, with a layout and illustrations that harken back to theme-appropriate medieval illustrations. They even have marginalia in there that look quite fun and appropriate. But despite being physically thicker than previous editions the contents also have been cut down to only player-facing rules, with only slight hints towards the background.
It turns out I will have to buy a not yet published GM's book to make use of these "Core Rules". Or buy a previous edition, because Pendragon never changed so much that I can't use the previous edition for this.
I find this quite annoying. Core Rules in my opinion are supposed to contain the actual core rules of a game that you need to actually play, not just a small subsection.
It doesn't help that other publications for Pendragon also get the treatment. It turns out the Great Pendragon Campaign, which started as a 78page supplement in first edition, now will be published in multiple books (I assume at least 5). And yes, it most likely will have a lot of content more, but still it will split up one book into five parts.
And outside of Pendragon I recently learned that the new edition of Cthulhu by Gaslight also will be split into a Players' and a GM's book. That also used to be a single book. Something that already annoyed me with the 7th ed. Call of cthulhu rules.
I know they want to make money, but Chaosium is lately overdoing it somewhat.
