Nintendo has ended pre-orders and opened general sales of the 'new' Switch OLED. In truth, this version of the console has the same specs as the well-established original unit - except of course for the new display type that has grown from 6.2 inches to 7 inches in this new version.
The OLED Model also has a new white Joy-Con colorway, although the classic neon red and blue colorway also remains an option. However, these new attributes seem to have driven it out of stock, shipping amenability or both on many sales platforms.
Amazon's national divisions in countries such as France do now list the console, although it may not arrive until October 14, 2021. This store appears to fall on the mild end of the Nintendo Switch OLED supply issue spectrum. This store lists the new variant at its recommended price of €350 (or ~US$350 in other regions), whereas this cost has been pushed up to as much as €469 on Amazon Germany (correct at time of writing).
Furthermore, the new console may not ship for several weeks from this version of the website. Meanwhile, Amazon US currently has limited units of the Switch OLED for sale, and now lists them for about US$600, to be delivered on around October 14, 2021 depending on your location.
Best Buy will sell the updated device at the normal MRSP; however, it has none in stock to order online, and it is not clear when they are coming back. On the other hand, if you have been holding out on your planned Switch purchase, and can live without the new screen type, now might be a good time to grab a deal on the "original" dockable Nintendo gaming machine.
