As of 2018, The Nintendo Switch now has a new version of Minecraft that uses the Bedrock system. This should be reflected in the store linked above so that users can purchase the game. You cannot purchase the legacy version of the game anymore.

Steps to reproduce:

1) Go to https://www.minecraft.net/en-us/get-minecraft

2) Select the "CONSOLE" option of "HOW DO YOU WANT TO PLAY".

3) Select "NINTENDO SWITCH".

4) Click on the green "BUY MINECRAFT" button.

5) You will be taken to a page about the legacy version of the game. The page states that this version can no longer be purchased.

To resolve this issue, the description should be changed for the Nintendo Switch version of Minecraft to note that the edition supports cross play. The "BUY MINECRAFT" button should link to this page instead: https://www.nintendo.com/games/detail/minecraft-switch/ since you are unable to buy anything on the page that you are currently directed to. You can purchase Minecraft on the page linked.
