Now that we see the rumor of HDMI-equipped XBOX 360, will those 150,000 people feel screwed to have bought the add-on?
that's a good question.
If the HDMI rumor is true, I'd bet some of the HD DVD owners may have preferred to have HDMI but really it's only useful (effectively) for 1080p TVs which as we know is still at a fairly low adoption rate.
wouldn't doubt though that of those who purchased an HD DVD player (this early) many may also have adopted a 1080p TV.
Personally I have a 1080i crt and bought the HD DVD player for 360 and so it would not bother me in the least.
Also, until we know more, it may be premature to imagine MS releasing an HDMI compatible box without a way to add it retroactively. May not be possible but until we know more (maybe tonight!? :smile it's not a big issue IMO but I'm sure you're right in that some will be disappointed.
