The successor to Nintendo Switch named Switch 2 will continue to be a hybrid console that can be played on TV and in portable mode, it will be launched
As others have chimed in if you do decide to buy a switch get the normal one if you’ll play on tv
Using the normal switches price as a reference if your gonna play in handheld a lot either go lite if you wanna save a buck (at the cost of connecting to a tv) or oled on the opposite end if you have money to burn. I got an oled as a gift and apart from more storage which was negated by everything going on a big micro sd card, all the improvements of the oled only come in handheld mode like bigger and oled screen (same resolution irrc) speakers, and stand.
