Let the hive mind of Engadget get that for you.
"I need help! I want a small pocket camcorder but I'm not sure which one to get. I don't want to fall into the hype of the Flip because I worry two hours won't be enough. What should I be looking for when considering a small camcorder and where can I get a good quality one with expandable memory? Thanks!"
That's a good point. People are assuming that the outputs of the 360/PS3 can't support HDMI. You never know there might be new cables in the future. But besides, even if they don't support HDMI, that could be good for consumers.
Imagine this scenario, six months after you purchase your 360+HD-DVD/PS3 to play HD movies, studios start using Image Constraint. Who's going to get caught? MS or Sony? Not if you have some movies that work and some that don't. Studios will be less inclined to use that feature if it limits half the installed base of devices, which could happen with the PS3 and Blu-Ray. You want more Blu-Ray or HD-DVD devices without HDMI because it takes away the desire to use Image Constraint.
