Just to confirm for anyone feeling a bit skeptical, this was a midnight (Pacific) release. So the game was available for full download and play at midnight Pacific. I downloaded it from my home at 1AM Pacific last night, and again this morning from my office at 7AM Pacific.
There is also a relatively small 1.01 patch after you install, so include that in any time calculations you might be doing.
