Back when Nintendo announced the OLED Switch, it noted that the dock would be sold separately. This dock, which also includes a LAN port, would be compatible with both the original and new version of the system. Now its online storefront is selling it in two different colors. Each one costs $69.99. [Thanks, Destructoid!]
Should someone buy the Switch OLED Dock, they will only get the dock in one of two colors. There is a basic black one. You could also get it in white. Like the current Switch dock, you can fold down the back to plug in the AC adapter, HDMI cable, and LAN cable. Rather than have the USB ports inside, there are two on the side of the dock for easy access. There is also a light in the bottom left front corner of the dock to show when it is connected.
Here are some pictures of both of the Switch OLED replacement dock models.
Nintendo did note that should someone buy a dock, they only get the OLED dock. This does not include any other parts. The company sells a refurbished AC adapter for $19.99. It offers HDMI cables for $7.99 each.
The Switch OLED replacement docks are now available through Nintendo.
