Several major websites reported earlier this month Bungie's revelation that Halo 2 would not be released in time for the 2003 holidays as many had expected. The news even went as far as major mainstream sites such as Reuters and BBC News.
Matt Soell made the original posts at Bungie.net and the HBO forum, and it was soon picked up by Louis Wu in the HBO news. After the news started to reach other sites, poena.dare compiled a list on HBO's forum.
There is no release date other than 2004 at this point.
