The article on gamespot says this:
The Longest Journey Home is the name of the game that would finish April’s story, but its existence depends, at this stage, on Red Thread reaching the stretch goal of two million dollars in its Kickstarter funding of Dreamfall Chapters. It is, perhaps, a long shot. But maybe the promise of another game is enough to inspire even more support, especially given how The Longest Journey Home would return to its roots: it is planned as a 2D point-and-click adventure akin to the original game, rather than as a 3D adventure in the manner of Dreamfall and Dreamfall Chapters. It would feature hand-painted backdrops, 3D character models, and, of course, a story penned by series creator Ragnar Tørnquist.
Dear me! We need that 2 million goal! I cannot pledge more, but if necessary near the end, and if it looks like the goal might be reached, I will have to think again.
