When it comes to announcing any kind of release date, it would be a fool’s errand to actually put any real stock in whatever date they give. These days, everything in gaming gets bumped back at least twice. Many things get bumped back more than twice.
For what it’s worth, a lot of gamers consider the Oled to be the “Switch 2” if you will.
For my opinion, I honestly don’t know where they could really go from here. They have VR, and have released a hybrid system which is one of the most popular Nintendo devices ever. So if you ask me, they have kinda shot them selves in the foot.
