I mean, when talking about battery life: the Switch 2 is shorter whilst the OLED has it last longer. The thing is, there are games I want to play that are exclusive to Switch 2 (like HW: Age of Imprisonment or DK Banaza), I do have a ToTK special edition OLED switch though. The only difference is performance (as it’s 1080p handheld supporting up to 4K at 120 fps).
They are increasing the console price worldwide, it’s ¥49,980 ($309 / 270€) as of now but later it’ll become ¥59,980 ($371 / 324€), so should I purchase it? Also the console will become $500 / 500€ (for now it remains at $450 / 470€) I’ve heard that a new variant is releasing in 2027 with a portable battery, even then is the console still worth purchasing?


I think any console buy should be based on whether it has games that you want to play.
If there are games that you want, but not enough of them, you can always wait, these games aren’t going anywhere, and as a bonus you can get the EU battery variant, even if they don’t release OLED version anytime soon.
If you are sure you’ll want to buy one in next couple of years, even without OLED, and don’t care about the EU variant, then this might be a good time to buy one, before the price increases.
It all depends on your situation.
