The last "current gen" DDR was released 10 years ago for the Wii. As for the "PC Version" they are making a browser-only game, I don't think I'd call that a "current gen" DDR game either, any more than the mobile games. If you're not dancing on pads with your feet, it's not DDR.
Here is somebody playing the browser only game Dance Dance Revolution V on a pad with their feet, so guess it is DDR 😂.
Jokes aside I don't understand why this is the only one of their PC ports that is browser based, while IIDX, Pop'n, Gitadora, SDVX, and Nostalgia are programs.
