I have no idea whether it's ok to post this link or not, but here's the most official looking website I could find...unfortunately not a hell of a lot of info, but it doesn't look like much of a tourney
Moscow Millions
A couple other things I've seen that are not official and may be rumors, but may not, are that the field is capped at 150 people and they expect it to fill up. However, the super sat the day before makes me think that maybe interest hasn't been as high as they are hoping.
