Been thinking about grabbing an OLED model for almost a year now, but the price is still just a bit too high. And of course Switch 2 is likely to land next year at some point. If there's no BC, it'll probably be the final push to make me pick up the current Switch.
Yeah my friend just bought a used OLED and they still go for like $300 around here. If you REALLY want that screen I guess.
I personally think that the original model is the best but that's only because it can be very easily modded. It all depends on what your priorities are, because the old ones also have a worse battery than the new models and the OLEDs. Of course, if you're going to hard mod and OLED then it doesn't matter much either.
I would just wait until we hear official news from Nintendo on Switch 2, though. I have no doubts that it will be backwards compatible. It's more a matter of how long you want to wait to be able to play the games. It's also worth noting that, according to leaks, the Switch 2 will not have an OLED screen and will be going back to the normal one, which is definitely a cost saving measure. So if you do REALLY want that OLED screen, it is likely that your only option for now is going to be the Switch OLED. Maybe they will release a version of the Switch 2 with an OLED screen but it will obviously be more expensive.
