The question was always whether or not to add one later. "Later" would probably end up being at least a year later, because nobody puts out such a revision too close to launch. So, BD is a valid choice at that point. HD-DVD was never really a choice for launch.

But if they added a drive later they don't really need to decide until later. And if they decide later, Blu-Ray will probably be the only choice as HD-DVD will probably choke on launch. It already has started its decline even before it has been released.

The issue isn't data capacity, it is audio/video play time. Therefore, one has to examine the application layer of both competing formats. Blu-ray has made it clear that they are only supporting MPEG-2 as the video codec (at a data rate of 24 Mbps - the same as D-VHS). AOD (HD-DVD) will use a new high efficiency codec, specifically either H.264 or Windows Media 9, which can achieve a superior picture quality to Blu-ray at data rates of 10-12 Mbps. So what does this mean: It means that even though a dual layer AOD disc will be only 30 Gbytes (compared to Blu-ray's 50 Gbytes disc), the AOD disc will actually hold more audio/video playtime!! So why doesn't Blu-ray adopt a high efficiency codec as well ... that is a very good question ... one reason would be that the already released Blu-ray recorders support only MPEG-2 video - so if Blu-ray switches to a more advanced compression scheme future pre-recorded movie titles won't play on the current Blu-ray recorders. As an aside, you will noticed that the other Blu-ray companies have not released Blu-ray recorders and in fact are waiting until the application layer is finalized for Blu-ray first - although my sources say that Sony (who is the is the defacto head of the Blu-ray consortium) is holding the line on MPEG-2 video compression to the dismay of several of the other companies. There is much more to be said, but I have already written too much - I will check back in a couple weeks with an update. Yours Truly, The DVD Guru I found this online.

Virtually every person I know with a Mac runs Microsoft Office. Of course you can also run Windows under Virtual PC (Microsoft also owns Virtual PC), but that's not quite as common. But I think your reason #3 for adopting Blu-Ray is the best. I wasn't of purchasing age during the VHS vs. Beta war so I mercifully got to avoid that one, and I am not looking forward to the HD-DVD vs. Blu-Ray battle!
