[quote name='electrictroy']WE ARE RUNNING OUT OF SPACE: If Square does what they usually do (push graphics' boundaries) we'll be seeing Final Fantasy upgraded from 640x480 to 1600x1080. That's roughly 5 times as many pixels requiring 5 times as much space. FF10 at 4.5 megs would become 25 megs.... requiring *3* dual-layer DVDs.
Or just 1 High-Capacity DVD. I think Square would rather choose the cheaper option of 1 disc, not 3.
ACCEPTANCE of High-Capacity DVD: You raise a good point about acceptance. But having ~50 million PS3s sitting on people's TVs, each capable of playing the new 1600x1080 movies, will go a long way towards that goal. You get 2 pieces of equipment (games & hdtv movies) for the price of 1.
Laserdisc & Super VHS never had that advantage.

Why do you keep saying 1600x1080? The 1080i and 1080p formats use 1920x1080 pixel resolution. The ratio between 1080i and NTSC's pixels per second is almost exactly 6:1.
Counting pixels is only a useful measure for uncompressed data. FFX's FMV is encoded to and played by the PS2's native MPEG-2 hardware. There are far better codecs now available that will be supported on next gen consoles. Their level of efficiency is substantially greater than that provide by MPEG-2 but even that scales up to greater efficiency with increased resolution. As the res goes up the chances increase of a single block being composed of identically colored pixels and using a minimal amount of data space after compression. While DVD uses an average data rate of about 5 megabits per second (with a maximum of 9.8 Mbps) broadcast HDTV uses a constant rate of 19.4 Megabits per second. So compared to DVD you get six times the visual data in only four times the data volume. And that is only comparing to DVDs that stay near the predicted average for the format. Superbit discs can run close to the 9.8 Mb maximum throughout.
the quality of HDTV broadcasts aren't the best for the most demanding scenes but the effect is no worse than commonly seen on DVDs compared to the uncompressed source.
The newer codecs improve things quite a lot. The compression ratio for the same quality increases quite a bit and allows a lot more to be done in the same space. This can be used to implement higher resolution or pack in much more
You can already buy Windows Media HDTV videos on regular DVD playable on a PC and some dedicated players. They have several DVDs available that demonstrate 720p and 1080i on ordinary DVD-ROMs using DVD data rates. The most popular, Terminator 2 Extreme Edition, uses a mode in between 720p and 1080i as a compromise because it can be used on a 1600x1200 monitor, which is the best most PC users are equipped to display. It's fairly demanding in hardware terms but the same was once true of MPEG-1. Dedicated players based on custom chips have shown that it can be done very cheaply if you commit silicon to the task. PC video cards are expected to start including hardware accelleration for the newer codecs in the coming generation.

It won't be a problem to feature FMV in HD modes on the Xbox 360. At worst a game might use a second DVD. It won't be a problem for developers like Square to support HD video on DVD if they chose to support those platforms. The amount of FMV found in the games most reliant on it still falls well short of feature film length and increasingly the game engines offer sufficient quality to do the job while keeping consistent with the appearance of the gameplay.
Putting Blu-ray in the PS3 has little to offer game developers until it becomes reasonable to produce a game that can only be played on a 1080i display. Other than that the only developer advantage is if Blu-ray movie playback is a big winner and leads to an improved installed base for the PS3.
