Don't see what's surprising about this. If anyone claimed otherwise then they have no clue.
X1 and PS4 support is still very strong, there are barely any next gen exclusives so there's no technical reason why Switch support should just vanish.
Though by next year that "could" drastically change.

Yeah the Switch can't be compared with the Wii U or anything for that matter, it's success ensures better 3rd party support than the past, anyway the size of the window for it to have any consequence is in Nintendo hands because a dlss Switch 2 equates to playable.ports.

The Switch will not lose any 3rd party support that it already didn't have to begin with. If anything, it has grown stronger through 3rd party exclusives and such. Monster Hunter Rise, BD2, Monster Hunter Stories, Project Triangle Strategy, and Resident Evil Outrage are a testimony to that.

Games like Immortals Fenix Rising for example were clearly developed with the Switch in mind, and enhanced for the other consoles.  Ubisoft in particular I can see having at least one game like this in development at all times. The growing Switch install base is too big to ignore.  Even Crash 4 from Activision simply recieved a slightly different art style to make the game work well on Switch.  For software that is not designed to push hardware limitations, this is also another route that can be taken for games that make sense on the platform.

Japanese games in particular don't really push hardware outside of a few big developers. Most of these companies have already either shifted to a Switch focus for their games, or at the very least started porting what USED to be thrown on the PS4 only. Given Nintendo's dominant stance in the region, and how it will not be changing anytime soon, it is safe to assume that Japanese 3rd party support will only get stronger overall if anything.

The games people like to highlight (CoD, RE8, Final Fantasy 16, etc) were never coming to Switch in the first place, because they never have. So to bring up bigger budget games designed strictly for the PS5/Series consoles is really just grasping for straws.

So yeah you really did not need 3 months, or even a year into the PS5/Series releases to be able to tell this narrative was complete BS. It has been obvious for years that nothing will change till the Switch 2 is on the horizon, based on sales figures and software trends that have been going on for the entirety of the Switch's life so far.

That's the thing, the Switch doesn't need to get ports of games built from the ground up for PS5 and Xbox Series. Between indies, Japanese devs, and the backlog of PS4/Xbone it already has plenty to draw on for years to come, and current AAA games have never been a major staple of its lineup.

It will stop getting modern AAA games but other than that third party support will stay strong for a while due to the massive install base. In particular indie and Japanese games will keep coming to the Switch in droves until the second half of the decade so its third party support will only really get killed off not that long before the PS6 and Xbox 5 release.

This year should be no problem for Switch, but the older the system gets the more we should see that demanding third party games won't get a Switch release anymore. Maybe we see the beginning of this next year. Non demanding third party games will be released until end of life of Switch, just like it was the case with Wii.

As long as the switch is successful, it will get support from companies that didn’t have their bridges burned. As far as the point about the ps5 Xbox4 stealing em: those consoles aren’t even really for sale at a normal price. They aren’t currently taking over.

Games like Fortnite, Overwatch and Rocket League that is playable even on low end devices will continue to exist despite the improvements in technology. Game developers know you dont need the best graphics out there to make a game that is playable by millions of people and still earn millions of $$$$.

I would imagine that Overwatch 2 will move the tech requirements forwards a few steps over Overwatch 1 which was already a 30fps title on Switch...

Diablo 4 will be interesting to see if it gets a switch port.

Honestly, this feels more like 3rd party support came really late on Switch. Devs were all against Ninty until sales made them change their minds lol
