I wish people would stop craving and talking about a potential switch 2. It's useless. For those who want to game now the switch works fine, is good hardware, has lots of games and new ones keep coming and it keeps selling new consoles. They could not release a new switch for the next 5 years and it wouldn't matter at all.
This is all about the nerds of the latest and hottest tech craving for something new. Most Nintendo players are not those type of people.
And it's obvious that whatever comes next will fully support and run the current the games the existing switch, if not they wouldn't be releasing new games for it.
So stay calm and keep playing.
Useless noise, so annoying.
