The very limited space for storage on the Switch has become a problem for lots of people as many downloaded games simply can't work without a bigger SD card than the one included with Nintendo's console. One of the bigger games that we've come across is Wolfenstein II: The New Colossus, which supposedly would weigh in at around 14 GBs.
But now Bethesda has seemingly changed its mind, although not by decreasing the size, but instead by severely increasing it. A new listing for the game says it upon release will need "at least 23 GB of free space will be required to download this software". How much more than 23 GB will be necessary is unknown, but investing in a big SD card for your Switch is probably a good idea because the games likely won't get smaller in the future.
