Hey legaiaflame,
Tell me about it! There is some serious reading out there. 
Must keep reading, though…
I probably couldn’t have put it better myself!
Do you think that if Team Andromeda or a member of their staff were to clarify a few things, it would spoil the mystery and story, or enrich it?
I guess it would depend what things they clarified. I’d personally like to know a bit more about the dragon itself (same or different dragons), and a bit more about the downfall of the Ancient Age. They could still keep some mystery, but I think reconfirming a few questionable details (for example, did the dragons terminate all of the active Towers? did the Towers wear down over time?) would do more good than harm.
The only things I truly want to know about are who the ancients truly were, what the ancient age was like (possibly flashbacks in future panzer games, if there are any future panzer games 
), and some insight on the Sky riders adventure with solowing.
I think if some of these major mysteries were clarified than some of the magic and mystery that makes the Panzer Dragoon world so intriguing would most certainly be lost. I actually like the fact that the Panzer Dragoon world gives us mysteries and vague clues to ponder about. It makes you think and wonder in your own way. I mean to tell you the truth I have written many theories about Panzer Dragoon Saga, and Orta that you can read here or at my PDS site, because there were so many things that needed explaining. 
Getting back to this topic, I have recently posted my Radgam theory in a more organized and visually pleasing manner on my PDS site, at this location www.panzerdragoonsaga.0catch.com/Theory6.html
I’m sure it will be more interesting with pictures pertaining to the theory and the quotes are italicized so its easier to read.
