Atlassian tend to release things "when it's ready", they rarely commit to specific dates, because there's no way to tell if something is ready until it's tested properly, and once it's been tested properly, then it's kind of ready to announce almost immediately. I imagine they will support IE10, but I don't think you'll get a firm date. As Felipe says, watch the supported platform pages.
