At the end of Orson Scott Card's "Shadow of the Giant",
Bean - with his 3 children having "Anton's key" turned on - flies from Earth on a newly developed fast messenger starship, hoping for one of the 2 outcomes - either he and his children will eventually die prevening the gene from spreading; or IF research into turning off Anton's key works and they can be cured. Bean himself is very skeptical of the likelyhood of that research working, and, at the end of his life, so is the Hegemon.
Are there any other works - "Children of the Mind" trilogy, some new books or short stories or Card's published future plans - that detail what happened to Bean after that?
Please note that I'm asking specifically about Bean's further story, not that of the single "missing" Bean's child that's covered in "Ender in Exile".
