Norway - Nintendo warns consumers that they might not be able to meet SNES Classic Edition demand

The short version of the message above is that Nintendo isn't sure they can meet the demand for the SNES Classic Edition. They're working with retailers right now to square things away, but as you probably guessed, grabbing one is going to be tough. If you can find a retailer to preorder through, that's your best bet. Other than that, it's online/in-store hunting.
