What we do know is that we don't know what we're looking for. It's possible we still won't know even if we find it. Perhaps it's not even some 'thing' to find. Perhaps we won't know until we sell it and perhaps even then we wont know but only Frontier will know the who when and where it's sold.
Because this search is so vague as they've said before "player actions can determine the course of the game" there's no reason to assume they are always upfront and specific like competing CG's. So much of the game has been in the form "here's a universe go run around in it to figure out how it works", we mostly know about how it works by testing efforts to debug where it looks broken so there's no reason to assume a game plot mechanism can't be hidden as well. Drew did say in his clarification post of what he meant to imply that we has referring to exploration data in an overall general sense.
As for clarifications posts, why bother. There's nothing anyone can say that can't be taken the wrong way and no clarification what won't require further clarification or magnification, amplification, de-noising, delousing, deconstruction, reconstruction, dereconstructon all the while risking turning yourself into the blackbox the mystery of the universe can be derived from firing a non-stop string of balls at and recording the direction of the bounces. So what if some tool like me spends months trying to decode the dark wheel symbol, there's more wrong turns than right anyway. We want you to only go down intended wrong turns but not unintended ones?
Just sayin there's other possibilities than find the easter egg and deliver it to a specific station. I think that's one of the least likely mechanisms.
Regards the transcript of the convo between Ed and Salome another commander chipped in with something like 'All Hail Salome,,,,Only the Children can carry the message",,,I edited it out because it wasn't between Ed and Salome, looked like some one peeping in with their personal roleplay and adds unnecessary smoke and contradicts what Salome was saying which due to the way Salome scrolled looked a prepared canned statement from beginning to end. I suggest people actually watch it and make up their own mind.
