Also the andyman, a guy with a great eye for news has noticed it was a rumored release date for Windows Live Mail plus the new @live and @windowslive domains will come out the next day. But over the last week all these rumors that have been revelaed were not true and have given the websites a bad reputation e.g. Win Future and The Hotfix.
I think people really need to find better sources, how do they even know the launch party is that day and then come to conclusions. The release maybe be before that date or after .... Well at least I think that, I would of thought they would of had a party after a release.
