You're wrong there. The good thing about history is that there is more of it each passing day! 
I'm quietly confident about the new "knights". With two new large "castles", there is bound to be lots of interesting new parts. Let's just wait for better pictures.
Best wishes

No more Victorian Theme, since a long time.
No more Western Theme, with the exception of an occasional limited edition release and/or a special
No more Ancient (Roman/Egyptian) Theme
A very dumbed down and partly discontinued Pirates Theme, with not a single English or French soldier anymore.
A new
Medieval Knights Theme that purely reflects SF & Fantasy battles and with nothing civilian in.
Wow, we should jump from joy that those 2 new "castles" will probably contain a few nice figures or accessories?
Once one could buy a 3666 castle and be excited about the castle itself as it came and all the klickies and stuff that came with it in the box, without having to technically alter walls to be able to build something else with it.
Once one could buy a realistic looking 3940 (big) Pirates Flagship, it came with a gundeck below where you could put 8 functional cannons, a nice captain hut with real windows below the quarterdeck, good colours, quality stickers, etc. It could be used as a trading galleon or a Navy frigate with only changing out some flags.
Even when they switched to System-X, one could buy f.e. a 3112 Harbour Prison Fortress and be very happy with it, and buy more of the same set to design & build a much larger fortress.
Plastic was thick and almost unbreakable.
Now they replace the entire medieval theme(s) with some small SF/Fantasy-looking "castles" that are made from extremely large (and ever thinner) wallparts and out of which one can´t build anything else, except when he or she has craftsmanskills to technically alter those parts.
Good luck with trying to build a large complex fortress, or even a simple wall around a Medieval city, out of the parts from these new castles. Good luck with using today´s blue or pink coloured dollhouse-façade as an 18th-century Governour´s Mansion for a Carribean Island harbour-city.
With the old(er) Playmobil buildings, figures, ships, wagons, etc. & etc. one could realistically and with great detail recreate an entire panaroma of historical cities and life from the Classic Civilisations, through the Dark Ages, the Medieval Centuries & the Renaissance all the way up to the Victorian Age. That is entirely impossible with what they release these days.
And then you say I´m wrong that the Good Days are gone? Where have you been the past decades?
And yes, children are not interested in History anymore and prefer Fantasy, "smart"phones, fast (volatile) stuff.
There was a survey in Belgium a few weeks ago, most of children aged around 12-14 don´t even know who Moses was. Julius Caesar, never heard of. Napoleon? That´s that gamble-provider, right?
When people forget about history, then they´ll make the same (severe) (historical) mistakes their ancestors did.
When I was a kid, I went to school, learned about history or life in general, and replayed / recreated that at home with my Playmo.
And though I don´t go to school anymore since several decades, today I still love to recreate historical life at home with my Playmo.
But I´m getting "old" (47 next month) and to me it seems a lot of folks are too busy swiping their dumbphones and have forgotten about the "Dark Ages" (the 1930s included).
Have they meanwhile noticed that China is doing an enormous military modernisation & build-up like Japan did in the 1930s and will soon be challenging the world and the US in particular for domination of the Pacific and it´s global, strategically important trade-routes? No.
Have they meanwhile noticed that China is at the same time also investing greatly in acquiring strategically important infrastructure & econnomic assets in Europe and Africa? No.
Have they noticed the growing "populistic" political influences in the West, somewhat similar to the 1930s? No.
Have they noticed that everything they do is being monitored, tracked and stored (by f.e. Zoogle and people like Zuckerberg), a plethora of personal data that is then sold on to governments and corporations? No.
Fantasy is great, but when you have nothing else it makes you dumb as hell.
History is great, it lets you understand the world and see how things work and how they are connected, but be carefull, if you do too much research and see/understand too much, it makes you frustrated, like me.
