Rossies Classic is a remake of the original Rossies game that will run on the Godot Engine, the game is expected to be available on PC, Mac, and Linux, they will also be a Web version available.
So what happened to the original Rossies Classic? Well, a playable demo had actually been released, although none of the sites or servers it was hosted on aren't up anymore, however, I have dug out an old zip file of the demo. So for those curious to see the original game that never was, now you can try it out, and wonder "what if?".
