I wouldn't hold my breath for an official price drop anytime soon. Nintendo rarely reduces prices on their current hardware, especially when it's still selling well. Maybe look for holiday bundle deals instead - that's typically how Nintendo offers better value.

Just grabbed an OLED during a Best Buy sale last month for $330. Keep an eye on retailer promotions rather than waiting for an official Nintendo price cut. They tend to keep MSRPs steady and let stores handle the occasional discounts.

Honestly, I think the OLED is worth the current price if you play handheld a lot. The screen quality difference is substantial. That said, keep an eye on r/NintendoSwitchDeals - they post when sales happen, which is more likely than an official price reduction.
