Last time when they said that a patch was "around the corner" it dropped in like a week I think, so I wonder if we can expect the same this time.
However, if it does drop that quickly, that would definitely mean no big new questline-based endings 'cause I don't think enough time has passed since launch to add something like that in (especially with all the other post-launch work)
I will hold on to the "new" and "optional" wording there, 'cause "new" hopefully implies something more than just an expansion of an existing one, and "optional" kind of sounds like something you can optionally (duh) earn instead of being offered regardless of what you do (like the rest of her endings).
However, am wholeheartedly prepared (resigned more like) for
some alternative variant of going out in the blaze of glory
and nothing more.
(Although will say, "caving to the shippers" would also be fine with me personally, ahah. Would not be that out of line with the way some other characters in this game can get downright fairytale-ish endings and the D&D-typical array of options at our disposal.)
