Valve needs to release statement on pronunciation of Eidolons

During qualifier games for SA casted by Mikelorus he would pronounce Eidolons as Eye-Dough-Lins, and most sources online seem to verify https://www.youtube.com/watch?v=eW-oPa5vrfk. However, the ever-intelligent twitch chat seemed to be irritated by this pronunciation, perhaps preferring Eye-Dough-Lons. We need to have a single answer to this question and Valve statements seem the best way to get everyone on the same side of an issue.
