The first release will be "Centipede," and the company is taking preorders on it via a Kickstarter campaign. It doesn't have the advantage of a reissued console like the SNES Classic where you get a ton of games in a single package. However, these have the advantage of looking amazing and being the kind of thing you could put on display when you're not using it.
New Wave Toys tells Thrillist "Centipede" is a part of a multi-game deal with Atari for what it calls "The Atari Collection." So, more games are on the way after "Centipede." The company will soon unveil a stretch goal on Kickstarter to unveil which game will come next.
The systems are expected to ship in spring 2018. Hopefully, there are more on the way. ("The Simpsons," anyone?)
