You're talking about two different things now. The controversy over console vs. mobile has to do with the business model and style of game (traditional vs. F2P). That distinction doesn't exist on console vs. PC. You may be right about consoles eventually being overtaken by PC and mobile, most likely no one cares whether they're playing games on handheld, console, PC, mobile, or their toaster as long as the games are good. The problem is with Pokemon's trend towards simplistic F2P games. If you're going to say that PC is replacing console, then you could just change it to "well, Game Freak isn't doing enough with PC".
Regardless, the point remains is that console and PC appeal to a different market that likes a different style of game from the simplistic F2P games of mobile, and in fact that sector is thriving. The PS4 is closing in on 100 million sales. The Switch has gotten off to a fast start and has already surpassed the lifetime sales of some of Nintendo's past consoles in just its first 2 years. And there are multiple games on both platforms selling 10+ million, especially large scale open world titles. So there is clearly a strong demand for high quality, full featured games that are heavy on exploration and content. So what are Game Freak and TPC doing to appeal to that segment of the market? Sure looks like nothing.
Sadly, anti-consumer practices don't always fail, so we can't count on that. It's most likely some combination of 1 and 3.
Also, the mobile spinoffs have been more than happy to capitalize on microtransactions.
What different resource pools? Pokemon Masters is being worked on by DeNA, yes, but the rest are all coming from Game Freak and TPC.
Sigh...
All right, I'll bite. What would you blame the lack of console spinoffs on?
