Good call, but the forums came up with the thought that Bioware moved the story to Andromeda waaaaay back when they first released concept art of a new galaxy map which looked suspiciously liked Andromeda (especially in the IR spectrum). That, in turn, spawned the "ark theory" and that Bioware would be moving the story to Andromeda. Myself and others participated in those discussions way back then, and many since, on why/why not this would be a good idea.
My stance on the subject has always been that whether it is a good idea or not is irrelevant - Bioware would move the story to another galaxy solely because it is way too tempting of a solution to the corner they wrote themselves into.
So, good job calling it, especially if you independently thought of it. But others here thought of it as well, and earlier, so the idea wasn't totally original.
I wont lie though, I did smile a bit while watching the video, wondering what Revan and all the other naysayers who were so vitriolic with their objection to Andromeda / ark theory must be thinking.
