A while ago MS put up a page for their new promotion which indicated that all new Xbox 360 owners would get a copy of Halo 3. However MS has since updated their page to clearly clarify that not everyone gets a free copy of Halo 3. The offer is only applicable to those with an old Xbox and Xbox Live in order to encourage them to upgrade.

Please note: This offer is only available to existing paid Xbox LIVE members on the original Xbox console (not Xbox 360) who fulfill the offer terms. For a brief period on November 16, 2007, an erroneous post on this site did not clarify that only those members on the original Xbox are eligible.

Original Xbox console users: Buy an Xbox 360. Migrate your paid Xbox LIVE subscription (for the original Xbox console) to Xbox LIVE Gold.
