Did that post seriously reference the phrase "writer soon" - yeah, somehow I just think this feature won't ever happen. They can't even do hood toggles when they were talking about those 3 months ago, or add in Nightmare mode, or fix Ilum after 5 months, etc. - the idea they're scripting and recording flirt options and editing cinematics strikes me as unlikely. And they fired the guy that promised this.
Has the new community manager said anything?
They already said they're not adding to companions in any of the grab bag they announced at E3.
