[quote name='The Mana Knight']Need me to bring up the article about Kojima wanting a dual-layered blu-ray disc to be ready for MGS4?
Also, look at Blue Dragon on 360, taking up three DVD9s. Enchanted Arms was suppose to have some high quality, HD CG cutscenes, but they had to be removed due to the limitations of the DVD9. Even Team Ninja wanted to include a HD intro for DoA4, but could not due to DVD9 not having enough space. The only reason MS made HD-DVD an add-on was because it wasn't out when Xbox 360 was out. If HD-DVD could have come out a year earlier, I guarantee the 360 would have been using it as a disc format.
I don't care about HD-DVD because blu-ray is the superior format in every way.[/QUOTE]
I agree Blu-ray is a superior format for data - but for video, it's a toss-up.
Xbox would have used the HD-DVD format out of the box had it been a single standard. But since Sony walked away from the DVD Forum and decided to compete, it was guaranteed the two formats would coexist for a period of time. Thus, Microsoft didn't want the X360 tied to a format that may be made obsolete before the end of the system's life cycle (divx, anyone?), or have to incur the cost of manufacturing these discs to keep the format afloat (Dreamcast, GD-ROM).
Sony, on the otherhand, has everything to lose by packaging Blu-ray with the PS3, but smart in that the PS3's internals can be upgraded. I will guarantee during the PS3's lifetime, since they are talking about a ten year span, you will see Blu-ray go the way of the UMD. Either next gen optical format doesn't have any legs for consumers, as things are already moving toward digital distribution.
