No way. I've had a standard Switch for four years this month. I play in docked mode around 80% of the time (possibly higher). Even if I played way more in handheld mode the few new features aren't worth it.
A Switch Deluxe (or whatever it would be called) still probably wouldn't be enough to entice me. So Switch OLED sure as heck won't.
Lifetime Sales Predictions
Switch: 144 million (was 73, then 96, then 113 million, then 125 million)
PS5: 105 million Xbox Series S/X: 60 million
PS4: 120 mil (was 100 then 130 million, then 122 million) Xbox One: 51 mil (was 50 then 55 mil)
3DS: 75.5 mil (was 73, then 77 million)
