Outstanding! What happens when the time is up? On SupCom Universe we left the countdown going up for a few year after release...
I'm guessing the countdown is supposed to be when it strikes midnight on August 10, making it August 11. Unfotunately, that may not necessarily be when MS makes it available on LIVE.
This does not match the 2-3am EST experiences I've had with other things, but I suppose times might have changed.
Generally 5am EST is when I've seen games become available. Periodically it takes longer -- sometimes up to 6pm. I doubt they will do that with a SoA XBLA game.
If it's released on regular xbla timing it will be between 8-10am in the UK wednesday morning, perfect timing for me to spend a free wednesday kicking arse in MNC!
