I am sure we all understand your wanting to know more, as I posted a request for more info, screen shots, etc... anything, a few days ago, and a couple of kind souls helped pointing me to a couple sites with interviews, etc. via using this forum, and I'm sure if you look back a few days in this forum you'll see it.
I believe that they don't let much info out less-so for reasons of not wanting to tip their hand, so to speak, to the competition, but I assume the main reason is that they don't want to tell us of something that they planned to put into the game, but is later realized they couldn't.
Once that is done, there are way too many unreasonable flame-the-game-maker type responses that tend to pop up.
It's sad, but I'm sure you all know how that story goes.
