Considering all of the stuff teased for 0.8 (i.e. 2nd hop on the New World, December Ski Trip, Dalia's Birthday) I find it unlikely that Orion is going to stay dead for long. My money's still on a stay in Limbo where Idriel has stated that time doesn't exist, which would allow him to go through a character development phase without having to worry about how much time has passed since Eternum's time seems to flow just as normal as it is in the real world (whereas Limbo is implied to be a realm detached from both). Then from there he could either get picked up by Caly or he revives through sheer libidoImean willpower.
