I'm grateful for all the replies so far.
I see that I'm not the only one that had that impressions. That means there is a concern (real or not)about this. I'm aware that it will not be the last.
Like I said, I saw patterns of things. I believe that the peak of the current form of Pathfinder is in the past. As it goes now, it will decline gradually. And like everything in the RPG world, it will cease or evolve.
To be honest, my point of view is tainted by nostalgia. I never had an interest in the 3rd edition of D&D. I was infuriated that my entire collection 2nd edition was replaced. My brother take the plunged on the new version from WOTC in 2000. When Pathfinder system replace or continue on the 3.5, my brother stopped. I take the relay. Now, I see Pathfinder takes options like the 2nd edition. Archetypes are Kits. The Ultimate series look likes the many brown and blue handbooks. It sounds like my good old days... my golden years.
Maybe, maybe I was burned in the past. To love a RPG that much (yes, I was a real fanboy of the TSR stuff) and to lose it all takes it toll. I'm now afraid that it will happens again. Even if history is never the same, sometimes it feel similar.
Now, if Paizo will avoid and learn from the mistakes from others. I'm happy with that. I will continue to support Pathfinder as long there is product that interest me.
My personal request will be to urge or plead Paizo to revive or create something similar of the setting Birthright. It's a good time with all the crazyness of the Game of Throne to have a setting that promote political backstabbing, alliance, etc., etc. Kingmaker opened a door, but for me it was just a part of the possibilities. The rules was more for the internal management and few external management with other kingdom.
I could add more things that I would like to see. I will stop now.
P.S.: I'm sorry for the sentimentality rant. It was long due for me to share.
