GamesIndustry.biz published an article where experts in the gaming industry share their predictions for the new year. One of the participants, Dr. Serkan Toto from Kantan Games, said that he expects Switch 2 to come in 2024. He stated that prices for both the console and games will rise. Also, in his opinion, new Nintendo console will likely be an iteration rather than an evolution.
"The time is finally here for a Switch successor, even though I can say a "Pro" model actually did exist and certain developers were already working with the dev kit. I believe the next hardware will drop next year for $400. There is a high chance that games will cost more, too: $70. The next system is also likely to be an iteration rather than a revolution. Nintendo might add some bells and whistles to the device, but it will be similar to the current Switch. And because there is Pokémon, and Pokémon is associated with handheld gaming, there is no way on earth Nintendo will drop the portability feature for their next big thing."
This prediction is interesting, considering different rumours and fan theories circulating in the community. For example, after Masahiro Sakurai said he's still creating games, some people implied that he is busy with the new Super Smash Bros. title.
Nothing has been officially announced, so we will have to wait and see if this prediction will be true.
