Neighbours Spoilers???

In Neighbours a lot of the main characters are leaving and the first spoiler I heard is that either Ned, Marco or Oliver die as they're all leaving. Anyone know which one it may be? I think it's most likely to be Marco as Carmella is leaving aswell. The second spoiler I heard is that Rosie and Frazer (who are also leaving) get some bad news about their baby which then turns into good news. I think that she is carrying twins but loses one and then is told that the other one has survived. Anyone else heard any of these?
