There is no record on Xcard's bounty, this project is closed. I think this project failed. Maybe you can ask the bounty manager directly. He is the one who more clearly provides information on the project he manages.
Yep, don't get your hopes up this project will come to life. If they are serious about developing a project they should always keep the community informed about their progress. After a long time there was no news, I saw that in September they updated their twitter and gave them the latest information. But that is not enough, because many people have been disappointed with the Xcard project.
