Oh man I love this thread. GaaS for Pokemon Switch, Pokken models for Pokemon Switch should happen, two versions are unnecessary because people are too stupid to realize they only have to buy one version and its all a conspiracy theory, woof. I am so glad that Gamefreak read the message boards and thankfully said, yeah don't be too excited, its still going to be Pokemon. Which means, guess what? None of the above thankfully will happen in the immediate future.
-GaaS already happens in the multiplayer, no need to seep into the actual single player, or to decimate previous single player features by bringing them back and using them only for multiplayer. Yes, lets bring back the Battle Frontier, but make it online only, and with rotating Battle Facilities because that's what everyone is doing, so Gamefreak obviously should! Really? Gamefreak bringing back the Battle Frontier would happen once they realize that is what people want, and if they do, then that would actually mean the single player would be something akin to Platinum or B2W2, not a GaaS snoozefest.
-The Gen 6 models are fine. Obviously the Switch would have improved shaders, probably even better textures. I can also see them making minimal changes here and there to allow for bump maps so that faces and what not won't be flat, but that's about it. And its perfectly fine, if not great.
-Two versions can still happen. Probably won't be 60, I can see them going with 50. And why should they still happen? Because that's Pokemon. It will always center around two version with unique things here and there so that people can not only share their collections, but their experiences. Gen 7 kinda went a bit further than usual in that department, and I can see the next games also doing that. Different boss battles, different story beats, its all good.
In general I am not some know it all, or consider myself superior to anyone else. But really, when it comes to predicting what or how Gamefreak will do something, everyone gets it wrong, including myself some times. Yes they follow trends, but they do not follow them in the same way everyone else does. Nintendo does have GaaS games, and I love them, but Pokemon is not the series for it. No matter how much online is integrated into the actual games, the matter of the fact is that there is still a core single player experience at the heart of it, and its that experience which drew us to the franchise and its critters in the first place. Gamefreak more than likely knows this, which is why I can't see them every adpoting that style beyond Seasonal Rated Matches or Cups. More tangible awards and a proper online hub world like the Splatoon Main Street thing? Sure. But no more than that. But yeah, beyond that, as I said above, things like the models, or the two versions, they won't and don't need to change at all.
