This is Nintendo's official trailer for the SNES Classic, which shows off some of its save state and rewind features.
Nintendo has allowed preorders to go live today, August 22nd, 2017. According to some outlets, Amazon and Best Buy's preorders went live in the middle of the night, then sold out within an hour. What's weird is that I was up during the time they went live, but I never got an alert. It might be a glitch, like the Walmart situation, and the preorders will be available later today sometime. Either way, more stores, including Gamestop, Target, and Toys R Us are supposedly opening preorders later today sometime. And went I spoke to GameStop, they expected to have some systems available on launch day for those without preorders, if they were willing to stand in line.
As for me, I jerry-rigged some code that lets me reload the GameStop webpage every minute and will be monitoring it all day. Good luck out there!
