There are already plenty of Xbox 360's out there but NONE of them have HDDVD built in, and last I heard Microsoft said they never will - it will always only be an add-on drive. The PS3 does of course have a Blu Ray built in but will have to shift some units before it becomes a seriously viable format. Standalone HDDVD players are much cheaper than their regular Bluray counterparts. I think (and hope) that BluRay wins the day, it's larger capacity makes for more features on ths discs.
