Anyone else think its MendicantBias?

So I was watching the trailer a while ago trying to piece it all together and Ive read some of the other threads saying that it might be a war sphinx or seeker. I was just wondering who else thinks its MBias and why?

Go to the Universe forums and look for the thread about the Ark Theory. It’s a good read and very plausible (and it includes Mendicant Bias).
