To be honest, I don't think any developer is smart/caring enough to have a formula for what they are doing years into the future(aside from game dev timelines).
I think Destiny is going to be something none of us expect (at least [i]most[/i] of it being unpredictable.) It seems like a lot of posters are making mountains out of molehills and frankly grasping at straws to try and glimpse Destiny. And it's a great goal, to be sure (I wish I had the dedication to put something like this together!). But imho, all this specal-uatin' is pretty pointless until we see more. That said, it was a good read/will be nice to ponder, Siffy. Maybe you're right and I'm just a pessimist.
