Stroud was talking about the "alien relic" noted in the timeline from FE2. He said it was significant and that they were defining it's role in the lore. At no point did he say anything that links it to the UA. He's saying "we plan to do something with the relic" and you're assuming that "something" is the UA. Perhaps it is, but to me that's conjecture at this point.
As for Braben, it's your interpretation that he changed the subject. I disagree; for me he simply spoke about the recent history of the subject rather than giving away anything coming up. But even if he did change the subject, I claim that the fact that he changed it to the UA is significant. "Thargoid" made Braben think "UA".
But you're right, we can't really settle either debate without some new information. Roll on 1.5/2.0.
It's quite clear that they are talking about the relic from the time line, but they keep calling it the 'unknown artefact'.
It's odd to say the least. I don't know what to make of it.
