Nintendo has announced it will extend availability of the SNES Mini/Classic Edition into 2018 for those in North America and Europe. That's a shift from its previous plans to only deliver the system until the end of 2017.

The announcement comes at a time when demand for the SNES Classic Mini is high, while supply remains low--at least for pre-orders. Nintendo acknowledged as much in a press release, saying today's news is "due to incredible demand" for the system. Those currently looking to purchase one are having extreme difficulty finding one in stores and online without paying an inflated price. Many retailers that have had the hardware available recently offered it in high-priced bundles.
