This statement is kinda ridiculous, and comes across as a pissing contest in disguise. Despite being on D&D systems, the companies are playing different games.
I can't help but get the feeling that some people in this forum are just playing "my daddy can beat your daddy" or want to see Paizo do poorly so that their "daddy" WotC/D&D 5e remains on its pedestal. I for one wish Paizo well. I hope that Pathfinder 2 does well beyond their own expectations. I want to see people play D&D, Pathfinder, and whatever else. More competition does the hobby well. And while it's nice seeing D&D regaining its stride, I would be saddened if Paizo and Pathfinder failed because they provide a different sort of game than D&D 5E. And while I do like D&D 5E, it's not perfect, and I think that I would become bored of D&D 5E if it's hegemony was unopposed.
PF was in a good market position. They choose to wait how much DnD would continue to sink with their new edition.
For a lot of people the sales and popularity of DnD 5ed is surprising and unexpected.
IMO PF missed an opportunity to knock out DnD.
They are now late for a new product and increase market share.
They will produce what they are good at: A complex evolution of 3.5 with a lot of options.
They have good chance to satisfy their player base and appeal those who wants a more complex game.
But I’m sure it won’t be trending as much as DnD.
