So the switch can run Forza or HZD? I'm confused, how is that possible when it barely runs BotW better than my WiiU?
XBox One couldn't run Horizon: Zero Dawn, while Snake Pass hasn't seen "significant upgrades" compared to the Switch version, which, BTW, had a lot less time and affection spent on it than the others, so, your point is!? Horizon: Zero Dawn was designed with the PS4 in mind, and optimised for that purpose. Similarly, PS4 couldn't run Forza - It wasn't designed for that purpose. X4 consoles couldn't run Nintendo Land or Super Mario Maker, or 5-player local multiplayer on Sonic & ASRT, or other Wii U titles and editions in their intended capacity, because they don't offer second screen support out of the box. That isn't a slight on either console, it's just the way they're designed. Still, I don't understand this preposterous idea that the Switch has showed its full potential at launch - If Wii U launch titles and "third party" port-jobs reflected the true potential of that hardware, then LOZ: Breath Of The Wild, Xenoblade Chronicles X and even Mario Kart 8 wouldn't have been possible on it in the first place.
LOZ: Breath Of The Wild is a Wii U title at heart. It was made for a console with a different architecture, etc., and designed primarily with the Wii U in mind. Simply putting it on more powerful hardware doesn't mean it will do everything better by orders of magnitude, especially when it wasn't optimised to a point of making the Wii U owner feel that they got a lesser experience. It's also worth remembering that there were games that performed better on 2013 PS4s than the PS4 Pro. Still, the worlds of LOZ: Breath Of The Wild and Xenoblade Chronicles X are bigger than that of numerous open world titles (The Witcher 3, for one...), combined in some cases, and it's no slouch on the hardware, given the level of physics-driven gameplay, and intelligence afforded to the wildlife. Furthermore, not one developer has spoken of "significant downgrades", while Bethesda has explicitly stated that they aren't in the business of downgrading their games - that publisher is supporting the Switch, and that should be all anybody needs to know. So, If the Switch doesn't get a game, it won't be due to its specs.
